I watched this video just before towing a travel trailer for the first time. Gotta be honest, thought it was a bit exaggerated but quickly learned you were spot on!!! Thanks for sharing!
an 8ft deisel 2500 made an incredible difference along with a Blue Ox WD hitch. We towed the same 30ft trailer with a capable v8 SUV but the difference in tracking and "fighting" the trailer continually was amazing. We almost bought a 1500 and are very glad we stuck to the plan. Great video. Glad I've never had to manually jam the brake controller to save lives at this point.
I have a Blue Ox sway max weight distribution hitch for my 35 foot tt, it helps. It does not sway so much as just pushes the whole rig slightly with a gusting cross wind. If you feel swaying coming on, 1) foot off accelerator and foot off brake if possible, 2) GENTLY squeeze the trailer brake. This will tend to stretch the trailer and truck straight. Stop sway before it starts. I have towed in some pretty nasty winds, and this helps. And go slow or stop in bad winds. I think my suspension air bladders help too. They kick down any bounce.
Very good advice. I prefer a neutral throttle or even slight acceleration rather than coasting before hitting the trailer brakes before going off throttle and on the tow vehicle brakes. Better outcomes. More control. In tow-haul mode, the downshift and compression can be just enough to lose control.
OK, if you have a PU with a single axle, get air bags! And a really good weight distribution hitch. Really, the air bags drastically reduce the bouncing. Weight distribution is so important I like the Blue Ox. Simple and works for me. Whatever you use, go slow and watch your flanks. Be very mindful of windy conditions when you are approaching a field after transit through tree lined terrain. Cross winds are hell.
Great explanation. I can personally attest to the effect of wheelbase. For all sorts of reasons we use an SUV as our TV, and a couple of years ago changed the TV from one with a 118" wheelbase to a 131". Our trailer and WD hitch (Blue-Ox Sway-Pro) remained unchanged (apart from height adjustments to fit to the new truck). With the old TV, driving in any kind of crosswind was a white knuckle affair, and I'd usually find myself dropping my speed to 80 km/h (50 mph). With the new TV, I can hold my speed at 100 km/h with no sway. However, you missed one critical factor: Speed. Since sway is a dynamic effect caused, in large part, by the airflow over the sides of the trailer, for any setup there is a critical speed, above which the tendency to sway will be amplified with each oscillation of the trailer. Therefore, one easy (and free) means to control sway is to slow down. A side benefit is the greatly reduced fuel consumption!
This was excellent, thank you! I just bought a 20’ Kodiak qb travel trailer that I’m pulling with my F-150. The dealer advised a weight distribution set up (it has an integrated sway control) and I wasn’t sure because it’s an additional $700. or so. However, watching your videos has convinced me and I’ve made an appointment to get it installed. Thanks again, your videos are very informative and educational.
Very good illustration and accurate explanation. Couldn't be better. Thanks to people like you, the internet is an incredible learning tool. Well done!
Fantastic explanation of how the weight distribution hitch works. I had the basic idea but seeing the physics of it really brought the importance of setting that hitch up right
If the axles or wheels are not aligned properly you will notice unusual wear on your tires! If you ow n and haul an RV, please read and follow your owners manual. Weights are hard for most of us to understand, but worth studying and following! A lot better than jack knifing your rig or seriously injuring yourself or family.
In addition or explanation, my brother and I have been driving professionally for over 30 years, we’ve seen and been through some interesting experiences. My brother jackknifed a set of triples on snowy road up by Idaho Falls. Not a good experience, I’ve rolled my car on the backroad to SunValley Idaho, just past Arco. Point is if you don’t follow the laws, of nature or man’s laws then there will be consequences! Some of which are very unpleasant!
After using 2 different friction style say controls I switched to a Hensley Arrow. Not only did their hitched worked as advertised, they have the best Customer Service I have ever seen in the travel trailer accessory business. When I sold my travel trailer and went with a motor home, they bought my Hensley Arrow back from me.
Bruce Marcotte I bought a used Hensley in a private sale via e-trailers. Hensley Mfg treated me like a new customer throughout. Never had an issue with the hitch. When I quit camping after buying a 3500 dually diesel (loved that truck) Hensley bought back the hitch, all the accessories and spare parts (new in box, plus 2 sets of sway bars) at more $ than they said they would! They sent me the box to put it all in! Their Customer Service was simply GREAT throughout (three drawbar swaps). Zero issues towing with a 1500, but I must have weighed both rigs half a dozen times or so to assure myself that everything was within spec. I went for the diesel strictly for the torque - towing in the mountains - and never regretted any of it.
Thank you! You are my new teacher! We are just getting into looking for a trailer to pull and have a 95 4x4 k1500 suburban with no towing package other than a ball hitch. Thanks to God 20 plus years ago I hauled three horses from Nebraska to nw Illinois through a blizzard with it without incident and want to be much smarter about towing now. You bet I will be following you and again thanks for caring and educating us. 🙏🏻
Weight distribution is a huge Factor Back when I was working for a motorcycle shop, I went about halfway across Texas pulling a 16 foot lowboy behind a half ton pickup with five big dressers and a side-by-side loaded on it Coming down this one long slow Hill the trailer started wagging the truck like you wouldn't believe Pulled over, move the side by side and two of the motorcycles further forward on the trailer, not a hint of sway the rest of the trip That's back when I was still green enough pulling trailers to pull a load like that with a half ton with a V6 🤣
I'm 26 and planning to buy a travel trailer by the end of the year and chase my acting career. I just got upgraded to a Tundra now I gotta get the trailer, there's so much to learn RV life
Thank you thank you thank you thank you thank you I would say that a million more times if I had the time. I have been trying to explain this to my sister she has a travel trailer and she just bought a pickup truck she was pulling the travel trailer with her minivan and that didn't work out too well. But now she has a pickup truck and I was trying to explain the sway bars and weight distribution hitch tour and I think this video will get it through to her so again thank you so much.
A buddy of mine tried coming to my rescue when my Suburban broke down. He showed up with his newer Suburban and a flat bed trailer. Got my Suburban loaded up and proceeded to get on the Freeway. We got up to about 40mph when the trailer started swaying back and forth. He is an excellent driver and knew when to gas the truck and when not to along with knowing not to slam the brake pedal through the floor. From the trailer swaying back and forth we took up both southbound lanes and almost went through a guard rail before he was able to get everything under control and stopped. My Suburban and moved around enough that my driver side rear tire was hanging off of the trailer and the drain plug and the axle of my Suburban got stuck on one of the diamonds of the diamond plate deck of the trailer. His was the first time he had used his Suburban to tow a vehicle with and found out a couple of days later that the leaf springs on the driver's side of his Suburban were bad. This was a seriously scary experience that everyone learned from and grateful as hell that no one was hurt.
Excellent !! I added an additional length to my RVs back porch and hauled an atv and generator on it. This is definitely effecting sway! I’m gonna have to eliminate these I think to make a safer ride
Thank you. I would have liked to hear more time discussing improper weight distribution on the hitch and how that causes inertial over correction between the the two body masses of the tow vehicle and the trailer. In my opinion, Wind is only a factor when it is significant. Tire alignment is a mechanical problem that occurs, but is not common. But improper weight distribution causes most of the scary and dangerous sway. That is why there are typically two systems incorporated in most camping and cargo trailer coupling systems. They are the sway control system, or braking systems that are added to weight distribution systems to limit sway, and the weight distribution system to bring the tow vehicle and the trailer into longitudinal and latitudinal alignment as a means to correct weight distribution.
I agree. Ive towed many years with both types of trailers. How the trailer is loaded front to back which produces tongue weight is really biggest factor in sway
Good explanation! An interesting aspect of the sway control is that when installed properly, the tongue weight doesn't cause your back end to squat down and front to point up! It loads the weight as if it is a bridge between the trailer and truck. Your sway control adds a substantial amount of weight to your front tires. Your trailer and truck should stay level.
Toy haulers are great, but when you strap down 2 heavy bikes in the back "garage" area of a travel trailer, counterbalancing for proper tongue weight is critical. Rear loaded trailers are the most dangerous thing on the road. They sway and wander with the slightest provocation. Losing your trailer, bikes, truck, and maybe even your life all in one fleeting moment of terror ain't why we RV. There are hitches that measure the tongue weight, as well as control sway. Spend the money, spend the time and do it right. This is supposed to be fun.
Excellent explanation and demo….it was easy to understand! As a newbie looking to possibly tow an RV in a couple of years this was extremely educational!
That is an excellent explanation of trailer sway. Also including the misalignment of the trailer tires cannot be overlooked. Many think it's only wind. Great video. Happy traveling, Lou.
Great explanatory video! But i do agree that weight disbursement in the trailer is critical as well...ie like w tractor trailers...proper weight disbursement over the axels...thru the body and up to the hitch. This is always something to take into consideration for all trailering.
One interesting factor with travel trailers is adding weight behind the axles of the trailer. I have heavy E bikes that I mounted on a hitch on my rockwood travel trailer. In addition ,If I have any water in my fresh tank, this weight is applied behind the axles causing a tenancy to sway. If I tighten up my sway control bars which are the blue ox system, this mitigates sway when I’m in gusty wind conditions. Also I make sure that my tanks are empty and I load my truck and trailer to counter the additional weight of the heavy bike rack. Very good video!
I have towed with the Reese Dual Cam Sway Control system since 2003. I have had no sway problems with this set up. It locks the truck and trailer together using a cam lock. Due to mechanical advantage, the trailer can't break the connection, but the truck can whenever it makes a turn. I have towed campers from 20' to 35', and have had no detectable sway. This system really works well, and is 1/10 as expensive as the Hensley.
I have a 2500 2 wheel drive truck I pull a 25 ft travel trailer with a 16 ft boat behind the trailer and the biggest things I have learned is you have to have a good % of nose weight to you trailer and make sure all the trailers truck and boat are as level as you can get them and I have very little trouble after that.
Thank you for a great video, the sign of a good teacher is when he can explain the subject matter in a way that the general audience can understand. Unlike some of your critics who try to impress themselves with complicated remedies.
Yes, proper setup is key! Have you considered weight distribution hitch storage? HITCHPORT Hitch and Spring Bar Mounts are the solution. The noise can also be quieted with Equal-i-zer Sway Bracket Jacket.
I agree with some of the other commenters that weight placement is also a HUGE factor in all this. But I think one thing you were sort of getting at without really articulating is that with a bumper pull when the trailer is trying to push sideways it has leverage on the tow vehicle due to the pivot point being about 4 feet behind the drive wheels, so the force is sort of amplified.
Knowing how to get out of that situation once your in it is key. Trailer brakes and throttle are two tools to help keep you off of your roof. But every situation is different.
Great video. I had to learn that no load balancing hitch means horrible wobble / sway. Now; I only get sway on long downhill curves which is likely a weight distribution issue with tongue weight being too high.
I find it unique the way it does it it almost reminds me of my bass boat when it starts trying to walk but in the bass boat you can go from 12 and 4 and jerked that thing about an inch to the left a couple of times and it will line out if it ever starts doing that but you can't do that with a pick up so the rules of the road versus the water seemed to be a little bit different I know it's a pain in the butt and this current camper reminds seems to be worse than the other one thought I would get on here and find a decent fix. This is an older camper a little bit older a little bit older that I chose to go with to drag back-and-forth to jobs on the road I'm sure the newer ones have fixed this problem a little bit.
Another thing is the length of travel trailer. The longer the trailer the greater the moment arm, and in conjunction with the wind you have the tail wagging the dog effect and greater sway.
As a Forklift driver who loaded Semi trailers, I was taught to put the heaviest part of a load ahead of the rear axles. This helps to keep the trailer from swaying, (tail wag) especially with tandem towing. I found that putting the majority of the load ahead of the axles made my camper tow better, careful not to exceed the tongue weight limits. Sway bars have improved since then.
Roy Davis general rule of thumb is 10-15% of the total weight should be tongue weight. More weight really only puts more strain on the tow vehicle but airbags or a good weight distribution hitch can alleviate most of that strain
Hi Roy I hear ya as far as weight distribution goes but I drive forklift too and only deal with lumber and MDF. Most of the loads I ship out need to be above the axles with less weight above the pins. I mainly deal with B-trains and the occasional flat deck if that matters.
Roy you have it correct. The problem with only 10% of the weight on the hitch is wind hitting the front of the trailer lifts it up, reducing tongue weight. Once the trailer starts lifting the hitch, you will sway.
@@gpecaut1 No not really unless your towing ar 120 mph stick with 10 to 12 %How do I know this Im one of the engineers that wrote the trailering guide for Chevrolet
Good visual demonstration. I'd suggest maybe a 'Part 2' to explain other factors that contribute to sway issues. 1.(sort of alluded to in the video...) The SIZE of the trailer - The 23' TT that I pulled with a '97 light-duty F-250 (7-lug wheels) had virtually no sway issues with a load-equalizing hitch. If you're towing a 30' Airstream, you might have issues. 2. Overhang - Are your tandem trailer wheels closer to the middle (bad), or further back (good - rear kitchen floor plans, for instance)?
Excellent video. Ive been driving Class A trucks for 20 years but I've never towed a trailer with a pick up truck. I got myself a 1 ton dually because it's better to have more than you need and not need it then to not have enough. First thing I did was to install airlift in the rear. After this video I have decided to pay the extra money for the fifth wheel trailer.
Our little camper is only 14’ and we pull with our Pacifica mini van. We were told by the dealership as well as the company (Travel Lite), NO sway hitch can or should be used when pulling this little camper with a vehicle that is double the weight of the camper.
I’ve been looking at a Ram 1500 ecodiesel, as I plan on towing a small-ish 28’ trailer. Your your video just made me rethink my bed length choice. And you may have helped lean me towards a 2500 dually instead of a 1500 single. Thanks I think you just cost me $20 grand. 🤣
With a 5th wheel trailer placement of the 5th wheel back and forward will control front to rear weight distribution on the truck.. Experience from 45 years of driving semi trucks..
Well done!! I definitely have a better understanding of what sway is. I use an old Curt weight distribution hitch without anti-sway bar. I learned that by moving more weight to the middle of the truck bed I was able to control sway much better without an anti-sway bar.
Another very well explained video that helps illustrate the many forces involve in towing trailers. Some of the following is in lamen's terms for the benefit of others who may be reading this. I know you from one of the Ford Truck forums I frequent. I know you know your stuff. One of the things that you left out that may have been noteworthy, is tires. It is astounding how many 1/2 ton trucks and SUVs have P-rated tires (Passenger car) standard. Swapping those out with an LT with a rating of E for instance will allow one to increase air pressure, thus increasing side wall rigidity. This will also help to make sure that the articulation of the entire suspension system resides where it should. I know this is a small factor when compared to the major causes you explained. But for the occasional weekender, simply changing a properly set up system with appropriate tire can be the final piece to the puzzle for a more enjoyable towing experience. Another thought.... For those out there who have purchased a package deal from an RV dealer (trailer and WD hitch), be mindful that it is almost impossible to properly set up a WD hitch to a tow vehicle when it is brand new at the dealer. Once the trailer is loaded with all of the gear for camping trips, it will almost undoubtedly change the behavior of the WD hitch. Be sure that if they assemble and install the system for you, the hitch and its components should be understood and adjusted by driver or owner of the vehicle. A basic understanding of how to properly adjust any WD hitch out there is a must if you consider yourself a conscientious, safe driver. It is just as important as working brakes and sound tires. Okay, rant over.
I have 36' toy hauler bumper pull that tows with no sway when no toys are in the back , the minute i put my touring bike in the rear garage its a handful . My solution was put weight back on to the front of the trailer with 4 milk crates of concrete in the forward storage compartment . Tows great now ..... weight distribution in the trailer is probably one of the biggest factors of sway .
Yep, I've pulled for many years with a 5th wheel and bumper pulls. With bumper pulls The biggest factor is how you load the trailer front to back. If you get hit by wind and your trailer is loaded right it may sway but will recover. If your loaded with no or little tongue you can start swaying almost immediately when getting up to speed even with a flat bed bumper pull with no wind. Applying the brakes when serious sway occurs helps because the tongue weight is increased and the trailer tires are not allowing as much swing. The leverage that a improperly loaded trailer has on the bumper of a vehicle is what causes sway and as steering wheel corrections are made it actually compounds the problem by slinging the trailer from side to side causing a type of centrifugal force that leads to a crash. This same force is what we do when we start pumping on a swing to get movement. Biggest factor improper loading which includes not having the right tow vehicle.
I never understood with those toy haulers why they have the "garage" in the back, that way when you load something you basicly take weight off the hitch.
I think there is one other factor in towing trailers that use a bumper trailer. Too much weight at the rear of the trailer means when the trailer/truck combo does move a bit, that excess rear weight on the trailer exerts a more powerful side to side leverage onto the trailer hitch. And there is less weight and traction on the tow vehicle rear tires
Ah, I finally understand: the majority of the wind "sail" area is ahead of the trailer wheels, but more importantly, ahead of the trailer's CG. This is very much like an unstable airplane. When the center of lift is ahead of the center of gravity, any perturbation is amplified until the airplane is uncontrollable. I see how load-distribution and pivot-projecting hitches fix that. Thanks!!
Good job. As mentioned in other comments, rearward trailer weight balance and surface area contribute to sway accelerating, leading to loss of control not only due to reduced traction but a more powerful lever rotating around the trailer wheels. Also, the lateral stability provided by the tires decreases with speed, parked rigs don't seem to sway, while those NASCAR guys get loose with no trailer at all😊.
Good video, though you didn't mention load distribution in the trailer, if there is too much weight behind the trailers axels it can cause major sway as well.
Nice job at explaining how sway works and what causes it. Nice that you included the Hensley hitch in your description. I have been towing trailers for 40 + years, and since 2007 when I bought my Hensley hitch, I have towed 3 different Trailers all on the 30' range with a 2007 Chevrolet 1 ton Express extended wheelbase van.We have traveled over 37,000 miles, and not once have we experienced ANY sway! And as to expense, yes they are expensive, but when you consider that they are connecting my investment that approaches $80,000.00, the $3,500.00 I spent on the hitch system amounts to a bit over 4% of the value I have running down the highway, and it is guaranteed for life to the original owner. I call that pretty cheap insurance. By the way, I do not work for nor am I compensated for making this comment or any other comment about the Hensley hitch. I have worn out various parts of the system, and I call them, they send me the replacement, bill me, and when they receive my damaged parts they credit me that payment. And yes, they play hell on my receivers. I have replaced one and had the second receiver modified to manage the stress.
Jeffory Newkirk LOL! The first thing I did when I got my '05 dually was to get rid of the (sub)standard frame mounted round cross beam receiver carrier Chevy supplied in that time frame with a "Class V" replacement. It wasn't really very expensive as I recall. Subsequently, I likely didn't tow nearly as much as you have, but I have similar sentiments to yours about the Hensley Hitch. Never leave home without it! Be Safe!
Very well explained video. I towed a skid steer yesterday but required 4x4 to get back out of the site. Forgot to kick it back off and had extreme sway. DO NOT TOW IN 4x4 ON HIGHWAY
Please make some mention of vehicle speed and how that affects the dynamics of sway ( i.e. resonance...). I find that simply slowing down can improve the stability. If your rig is prone to sway, reducing your speed might allow you to get where your going more safely until you can make improvements.
There's a video that shows a trailer on a belt drive system and they move the weight around to show the effects of weight distribution. Pretty interesting.
Also ideally speaking with 5th wheel your hitch should be above your drive axle or slightly ahead. Proper 5th wheel placement places weight on your steer tires too making your front end more stable.
A different type of hitch over here in the UK The ball connection on the vehicle is clamped down after the trailer is connected stops snaking and gives better stability. In the UK we are only permitted up to 60 mph even this can be too fast in some circumstances. It sounds wrong to clamp the towing vehicle to the towed vehicle,you would assume the ball and hitch would not turn,but it does,and secondly when reversing the tite hitch stops the trailer from too much outrunning giving much more control
Big thing forgotten is tire sidewall flex. This is something nobody talks about. The sidewall flex of one set of rear LT tires with four sidewalls and a short wheelbase truck creates an angle deflection of the towing vehicle greatly exaggerated over that of a longer wheelbase truck or a dually truck with eight sidewalls. Once those tires flex and take the rear of the truck off center line your instinct is to steer into it and then the pendulum effect begins.
I wish they would come up with sliding tandem axles on these trailers. If you could slide your tandem to the back or a foot or two from the rear, I believe these trailers would ride alot better.
34' bumper pull tag trailer no sway bars ever. My trick I've learned how to slow down save gas mileage wear and tear on everything. and keep my electronic brake close at hand if needed. I never even put the sway bars on. they're hard on the trailers tongue and have completely snapped some trailer tongues off.
I watched this video just before towing a travel trailer for the first time. Gotta be honest, thought it was a bit exaggerated but quickly learned you were spot on!!! Thanks for sharing!
Heading down in a couple hours to pick my new trailer up. I drive truck for a living. Weight distribution makes a world of difference.

We got a Hensley Arrow hitch and we don’t even know what sway is anymore. So glad we had it towing across the Great Plains. Well worth it.
Nice video...... I spent big bucks on an EQUALIZER unit from Utah. Took some time to install but haven't had any problems
Best explanation I've seen of weight distribution and sway control.

Weight distribution is a huge Factor
Back when I was working for a motorcycle shop, I went about halfway across Texas pulling a 16 foot lowboy behind a half ton pickup with five big dressers and a side-by-side loaded on it
Coming down this one long slow Hill the trailer started wagging the truck like you wouldn't believe
Pulled over, move the side by side and two of the motorcycles further forward on the trailer, not a hint of sway the rest of the trip
That's back when I was still green enough pulling trailers to pull a load like that with a half ton with a V6 🤣

Thank you. I would have liked to hear more time discussing improper weight distribution on the hitch and how that causes inertial over correction between the the two body masses of the tow vehicle and the trailer. In my opinion, Wind is only a factor when it is significant. Tire alignment is a mechanical problem that occurs, but is not common. But improper weight distribution causes most of the scary and dangerous sway. That is why there are typically two systems incorporated in most camping and cargo trailer coupling systems. They are the sway control system, or braking systems that are added to weight distribution systems to limit sway, and the weight distribution system to bring the tow vehicle and the trailer into longitudinal and latitudinal alignment as a means to correct weight distribution.
I agree. Ive towed many years with both types of trailers.
How the trailer is loaded front to back which produces tongue weight is really biggest factor in sway
Good explanation! An interesting aspect of the sway control is that when installed properly, the tongue weight doesn't cause your back end to squat down and front to point up! It loads the weight as if it is a bridge between the trailer and truck. Your sway control adds a substantial amount of weight to your front tires. Your trailer and truck should stay level.
If a bad sway occurs use the electric trailer break controller to slow the trailer and the tow vehicle
Toy haulers are great, but when you strap down 2 heavy bikes in the back "garage" area of a travel trailer, counterbalancing for proper tongue weight is critical. Rear loaded trailers are the most dangerous thing on the road. They sway and wander with the slightest provocation. Losing your trailer, bikes, truck, and maybe even your life all in one fleeting moment of terror ain't why we RV.
There are hitches that measure the tongue weight, as well as control sway. Spend the money, spend the time and do it right. This is supposed to be fun.
Excellent job in explaining a complex problem in understandable terms.
Amazing explanation. You did great
Thank You for this I've been towing trailers for years, and your explanation of the Weight Distribution Hitch cleared up some gray areas for me!!
Wish i saw this before i bought a 45k travel trailer!Great vid,and if i get another rv it'll be a 5th wheel....lesson learned🇨🇱
Excellent explanation and demo….it was easy to understand! As a newbie looking to possibly tow an RV in a couple of years this was extremely educational!
Slow the trailer, eliminate the sway. Use the brake override and feather it with experience. Do not fight physics.
That is an excellent explanation of trailer sway. Also including the misalignment of the trailer tires cannot be overlooked. Many think it's only wind. Great video. Happy traveling, Lou.
Except it's not alignment of the he tires, it's alignment of the axel.
Also, a very essential part of the "complete" system is the Brake actuator. GOTTA have one! Can't emphasize this enough!
Great explanatory video! But i do agree that weight disbursement in the trailer is critical as well...ie like w tractor trailers...proper weight disbursement over the axels...thru the body and up to the hitch. This is always something to take into consideration for all trailering.
This is exactly why I got a 5th wheel. Super safe towing and no tail wagging the dog.
One interesting factor with travel trailers is adding weight behind the axles of the trailer. I have heavy E bikes that I mounted on a hitch on my rockwood travel trailer. In addition ,If I have any water in my fresh tank, this weight is applied behind the axles causing a tenancy to sway. If I tighten up my sway control bars which are the blue ox system, this mitigates sway when I’m in gusty wind conditions. Also I make sure that my tanks are empty and I load my truck and trailer to counter the additional weight of the heavy bike rack. Very good video!
I have towed with the Reese Dual Cam Sway Control system since 2003. I have had no sway problems with this set up. It locks the truck and trailer together using a cam lock. Due to mechanical advantage, the trailer can't break the connection, but the truck can whenever it makes a turn. I have towed campers from 20' to 35', and have had no detectable sway. This system really works well, and is 1/10 as expensive as the Hensley.
This video may be the reason we go with a fifth wheel instead of a travel trailer. Super helpful!
Great video I learned a lot.
You have a real talent for making useful videos. Wow.
I have a 2500 2 wheel drive truck I pull a 25 ft travel trailer with a 16 ft boat behind the trailer and the biggest things I have learned is you have to have a good % of nose weight to you trailer and make sure all the trailers truck and boat are as level as you can get them and I have very little trouble after that.
Best video I’ve seen on sway yet, thanks
Thank you for a great video, the sign of a good teacher is when he can explain the subject matter in a way that the general audience can understand. Unlike some of your critics who try to impress themselves with complicated remedies.
Genius explanation and illustration! Thanks so much!
Every travel trailer owner should watch this video 👍
Yes, proper setup is key! Have you considered weight distribution hitch storage? HITCHPORT Hitch and Spring Bar Mounts are the solution. The noise can also be quieted with Equal-i-zer Sway Bracket Jacket.
I agree with some of the other commenters that weight placement is also a HUGE factor in all this. But I think one thing you were sort of getting at without really articulating is that with a bumper pull when the trailer is trying to push sideways it has leverage on the tow vehicle due to the pivot point being about 4 feet behind the drive wheels, so the force is sort of amplified.
Knowing how to get out of that situation once your in it is key. Trailer brakes and throttle are two tools to help keep you off of your roof. But every situation is different.
Never pull the trailer trolley brake. A sure way to jack knife.
Great video. I had to learn that no load balancing hitch means horrible wobble / sway. Now; I only get sway on long downhill curves which is likely a weight distribution issue with tongue weight being too high.
I find it unique the way it does it it almost reminds me of my bass boat when it starts trying to walk but in the bass boat you can go from 12 and 4 and jerked that thing about an inch to the left a couple of times and it will line out if it ever starts doing that but you can't do that with a pick up so the rules of the road versus the water seemed to be a little bit different I know it's a pain in the butt and this current camper reminds seems to be worse than the other one thought I would get on here and find a decent fix. This is an older camper a little bit older a little bit older that I chose to go with to drag back-and-forth to jobs on the road I'm sure the newer ones have fixed this problem a little bit.
instant props on intro bass riff
Excellent vid. Had no idea about the "technical" aspect but this will change the way I drive.
When I was towing a travel trailer, an 18 wheeler passing me was my biggest scare. Good input Big.
Very helpful video! I ran into a sway issue the first time I took my trailer on the highway. Scary stuff.
Great video. Great information in a very understandable way. From a 40 + year licensed engineer.
The very best explanation I have seen and I have seen too many
Another thing is the length of travel trailer. The longer the trailer the greater the moment arm, and in conjunction with the wind you have the tail wagging the dog effect and greater sway.
As a Forklift driver who loaded Semi trailers, I was taught to put the heaviest part of a load ahead of the rear axles. This helps to keep the trailer from swaying, (tail wag) especially with tandem towing. I found that putting the majority of the load ahead of the axles made my camper tow better, careful not to exceed the tongue weight limits. Sway bars have improved since then.
Roy Davis general rule of thumb is 10-15% of the total weight should be tongue weight. More weight really only puts more strain on the tow vehicle but airbags or a good weight distribution hitch can alleviate most of that strain
Hi Roy I hear ya as far as weight distribution goes but I drive forklift too and only deal with lumber and MDF. Most of the loads I ship out need to be above the axles with less weight above the pins. I mainly deal with B-trains and the occasional flat deck if that matters.
Roy you have it correct. The problem with only 10% of the weight on the hitch is wind hitting the front of the trailer lifts it up, reducing tongue weight. Once the trailer starts lifting the hitch, you will sway.
@@gpecaut1 No not really unless your towing ar 120 mph stick with 10 to 12 %How do I know this Im one of the engineers that wrote the trailering guide for Chevrolet
Thanks for creating this, impressing the importance of WDHitches and why it all happens.
Wow, very very good presentation, I just learned a thing or two. Very good, ty!!!
Good visual demonstration. I'd suggest maybe a 'Part 2' to explain other factors that contribute to sway issues. 1.(sort of alluded to in the video...) The SIZE of the trailer - The 23' TT that I pulled with a '97 light-duty F-250 (7-lug wheels) had virtually no sway issues with a load-equalizing hitch. If you're towing a 30' Airstream, you might have issues. 2. Overhang - Are your tandem trailer wheels closer to the middle (bad), or further back (good - rear kitchen floor plans, for instance)?
Excellent video. Ive been driving Class A trucks for 20 years but I've never towed a trailer with a pick up truck. I got myself a 1 ton dually because it's better to have more than you need and not need it then to not have enough. First thing I did was to install airlift in the rear. After this video I have decided to pay the extra money for the fifth wheel trailer.
Great explanation. I'm sure a lot of people are going to benefit from it.
Our little camper is only 14’ and we pull with our Pacifica mini van. We were told by the dealership as well as the company (Travel Lite), NO sway hitch can or should be used when pulling this little camper with a vehicle that is double the weight of the camper.
Loved your explanation. Shared with my MeWe group.
PERFECT . . . Answered ALOT of Questions I have been looking for. THANKS GREATLY . . . FANTASTIC VID . . .
I’ve been looking at a Ram 1500 ecodiesel, as I plan on towing a small-ish 28’ trailer. Your your video just made me rethink my bed length choice. And you may have helped lean me towards a 2500 dually instead of a 1500 single. Thanks I think you just cost me $20 grand. 🤣
Thanks for the education... Watching trailer sway accidents on RUclips looks pretty terrifying. Good to know how to keep it from happening to oneself.
With a 5th wheel trailer placement of the 5th wheel back and forward will control front to rear weight distribution on the truck.. Experience from 45 years of driving semi trucks..
Well done!! I definitely have a better understanding of what sway is. I use an old Curt weight distribution hitch without anti-sway bar. I learned that by moving more weight to the middle of the truck bed I was able to control sway much better without an anti-sway bar.
what type of weight do you use and around how much weight?
Another very well explained video that helps illustrate the many forces involve in towing trailers.
Some of the following is in lamen's terms for the benefit of others who may be reading this. I know you from one of the Ford Truck forums I frequent. I know you know your stuff.
One of the things that you left out that may have been noteworthy, is tires. It is astounding how many 1/2 ton trucks and SUVs have P-rated tires (Passenger car) standard. Swapping those out with an LT with a rating of E for instance will allow one to increase air pressure, thus increasing side wall rigidity. This will also help to make sure that the articulation of the entire suspension system resides where it should.
I know this is a small factor when compared to the major causes you explained. But for the occasional weekender, simply changing a properly set up system with appropriate tire can be the final piece to the puzzle for a more enjoyable towing experience.
Another thought.... For those out there who have purchased a package deal from an RV dealer (trailer and WD hitch), be mindful that it is almost impossible to properly set up a WD hitch to a tow vehicle when it is brand new at the dealer. Once the trailer is loaded with all of the gear for camping trips, it will almost undoubtedly change the behavior of the WD hitch. Be sure that if they assemble and install the system for you, the hitch and its components should be understood and adjusted by driver or owner of the vehicle. A basic understanding of how to properly adjust any WD hitch out there is a must if you consider yourself a conscientious, safe driver. It is just as important as working brakes and sound tires.
Okay, rant over.
I have 36' toy hauler bumper pull that tows with no sway when no toys are in the back , the minute i put my touring bike in the rear garage its a handful . My solution was put weight back on to the front of the trailer with 4 milk crates of concrete in the forward storage compartment . Tows great now ..... weight distribution in the trailer is probably one of the biggest factors of sway .
Yep, I've pulled for many years with a 5th wheel and bumper pulls. With bumper pulls The biggest factor is how you load the trailer front to back. If you get hit by wind and your trailer is loaded right it may sway but will recover. If your loaded with no or little tongue you can start swaying almost immediately when getting up to speed even with a flat bed bumper pull with no wind. Applying the brakes when serious sway occurs helps because the tongue weight is increased and the trailer tires are not allowing as much swing. The leverage that a improperly loaded trailer has on the bumper of a vehicle is what causes sway and as steering wheel corrections are made it actually compounds the problem by slinging the trailer from side to side causing a type of centrifugal force that leads to a crash. This same force is what we do when we start pumping on a swing to get movement. Biggest factor improper loading which includes not having the right tow vehicle.

I never understood with those toy haulers why they have the "garage" in the back, that way when you load something you basicly take weight off the hitch.
Perfect explanation, thanks. I will now buy a sway control system knowing just exactly why!
I think there is one other factor in towing trailers that use a bumper trailer. Too much weight at the rear of the trailer means when the trailer/truck combo does move a bit, that excess rear weight on the trailer exerts a more powerful side to side leverage onto the trailer hitch. And there is less weight and traction on the tow vehicle rear tires
Excellent video! Thank you for your time and effort.
You do such a great job explaining! Thanks
Ah, I finally understand: the majority of the wind "sail" area is ahead of the trailer wheels, but more importantly, ahead of the trailer's CG. This is very much like an unstable airplane. When the center of lift is ahead of the center of gravity, any perturbation is amplified until the airplane is uncontrollable. I see how load-distribution and pivot-projecting hitches fix that. Thanks!!
Good job. As mentioned in other comments, rearward trailer weight balance and surface area contribute to sway accelerating, leading to loss of control not only due to reduced traction but a more powerful lever rotating around the trailer wheels. Also, the lateral stability provided by the tires decreases with speed, parked rigs don't seem to sway, while those NASCAR guys get loose with no trailer at all😊.
Good video, though you didn't mention load distribution in the trailer, if there is too much weight behind the trailers axels it can cause major sway as well.
Nice job at explaining how sway works and what causes it. Nice that you included the Hensley hitch in your description. I have been towing trailers for 40 + years, and since 2007 when I bought my Hensley hitch, I have towed 3 different Trailers all on the 30' range with a 2007 Chevrolet 1 ton Express extended wheelbase van.We have traveled over 37,000 miles, and not once have we experienced ANY sway! And as to expense, yes they are expensive, but when you consider that they are connecting my investment that approaches $80,000.00, the $3,500.00 I spent on the hitch system amounts to a bit over 4% of the value I have running down the highway, and it is guaranteed for life to the original owner. I call that pretty cheap insurance. By the way, I do not work for nor am I compensated for making this comment or any other comment about the Hensley hitch. I have worn out various parts of the system, and I call them, they send me the replacement, bill me, and when they receive my damaged parts they credit me that payment. And yes, they play hell on my receivers. I have replaced one and had the second receiver modified to manage the stress.
Jeffory Newkirk LOL! The first thing I did when I got my '05 dually was to get rid of the (sub)standard frame mounted round cross beam receiver carrier Chevy supplied in that time frame with a "Class V" replacement. It wasn't really very expensive as I recall. Subsequently, I likely didn't tow nearly as much as you have, but I have similar sentiments to yours about the Hensley Hitch. Never leave home without it! Be Safe!
Wow thanks for this video, really helps to understand what going on with the trailer. :)
Very well explained video. I towed a skid steer yesterday but required 4x4 to get back out of the site. Forgot to kick it back off and had extreme sway. DO NOT TOW IN 4x4 ON HIGHWAY
Please make some mention of vehicle speed and how that affects the dynamics of sway ( i.e. resonance...). I find that simply slowing down can improve the stability. If your rig is prone to sway, reducing your speed might allow you to get where your going more safely until you can make improvements.
There's a video that shows a trailer on a belt drive system and they move the weight around to show the effects of weight distribution. Pretty interesting.
Also ideally speaking with 5th wheel your hitch should be above your drive axle or slightly ahead. Proper 5th wheel placement places weight on your steer tires too making your front end more stable.
A different type of hitch over here in the UK The ball connection on the vehicle is clamped down after the trailer is connected stops snaking and gives better stability. In the UK we are only permitted up to 60 mph even this can be too fast in some circumstances. It sounds wrong to clamp the towing vehicle to the towed vehicle,you would assume the ball and hitch would not turn,but it does,and secondly when reversing the tite hitch stops the trailer from too much outrunning giving much more control
Thank you!! I guess I should have my truck bed weight, gear, distributed behind the cab rather than closer to the tailgate???
Big thing forgotten is tire sidewall flex. This is something nobody talks about. The sidewall flex of one set of rear LT tires with four sidewalls and a short wheelbase truck creates an angle deflection of the towing vehicle greatly exaggerated over that of a longer wheelbase truck or a dually truck with eight sidewalls. Once those tires flex and take the rear of the truck off center line your instinct is to steer into it and then the pendulum effect begins.
I wish they would come up with sliding tandem axles on these trailers. If you could slide your tandem to the back or a foot or two from the rear, I believe these trailers would ride alot better.
Very well done one of the best videos on youtube well informed. Thanks
Great job on the video explain sway how it can effects the truck and trailer.
I love my Equilizer hitch.
34' bumper pull tag trailer no sway bars ever. My trick I've learned how to slow down save gas mileage wear and tear on everything. and keep my electronic brake close at hand if needed. I never even put the sway bars on. they're hard on the trailers tongue and have completely snapped some trailer tongues off.
Hensley arrow really really works ,its expensive but worth the money
