    Bought this truck after our 2017 ram 2500 Cummins left me stranded on Washington hi-way 28 last year. 78k miles on the ram when the def plugged up and the turbo controller malfunctioned while towing 9k pounds. Miss the exhaust brake but love this truck more in every other way. Smoother, quieter and more comfort. No more turbo engines or diesels for this family!

    I’ve been towing with the 6.6 and the six speed with a much lower weight - about 7000 pounds - and it’s been great. I don’t really care much about acceleration but I love our the low RPMs I get going uphill. That engine does not seem to be working hard.
    As always excellent objective overview - good luck with the new shop!

      What kind of MPG do you get when you aren't towing? I'm hearing 15-18 is about normal for these. I'm considering either a 6.6L gas 3/4 ton or a 6.2L half ton with the max tow package. Our enclosed trailer is about the same weight (7500 lbs), but our boat trailer is even lighter.

    We have a 2024 GMC 3500 HD. We have towed a 5000 lb travel trailer from BC to Nova Scotia, returned empty, and are now towing our 42 foot 5th wheel, 16,800 lb gross. The truck has been excellent throughout, save for the fuel economy. With the 5th wheel, after 2100 miles (through the US), mpg is 7.5.

    A couple things about MPGs : yes, weather will adjust the friction of the tires and create resistance and will affect the cruise control. I have zero clue as to whether or not Canada regulates their unleaded with a “winter blend,” which usually impacts our fuel economy in the states. Added weight? I am guessing the trailer’s wood planks are not impermeable, and when you’re talking about that much surface area, the water weight is nothing to sneeze at.
    The winter/spring testing is valid and useful! It’s just not quite apples to apples.

    • @daveallen7767
      @daveallen7767 8 месяцев назад +1

      We all get lower MPG in winter or cold spring temps. Air density higher so greater wind resistance, fluids like axle grease all have higher viscosity, and wind conditions change day-to-day

    Love the review; I think weather plays a huge part in this test, you could have had a strong head wind going up that hill, and for fuel efficiency I bet you're still on winter gas. My bet is if you redid this in 3 months on a beautiful calm summer day like the 6 speed was tested at, you'd find better fuel efficiency and less RPMs going up that hill, as somebody who tows RVs very frequently there is a huge difference between wind/rainy days and calm sunshiny summer days. Still, obvious from your run here that it's a better truck all around.

    Owner of 24' Custom trim Crewcab standar bed. . 2500. I don't tow a lot, but I am always ready. Paid $58K and has been an amazing truck. The 10spd give a lot more range and power points. The LT8 is a drinker towing but empty is not that bad, I do 16-17 mpg hwy and city 11-12 mp, and I have front and rear metal bumpers brush guard. Around 350 lbs, and diamondback back cover (200lbs). The trick for fuel efficiency is inflate tires. I do 68 front and 73 back , all 4 go ip 4 to 5 points once rolling. Bumpy ride but more efficiency and less tire wear.
    Is an HD truck, not a car. GM keep trusting the old school technology. Nothing fancy on Custom trim, normal gauges, no turbo, simply design, simple performance that have durability , no doubt.
    6.6 LT8 vs 7.3 Godzilla, IMO the 6.6 goes beyond. Longevity, but the 7.3 has more power.
    Actual pulling numbers are insane. A beast of truck.

    It's basically a stroker 6.0L V8 right? That's almost certainly an extremely reliable setup. They've switched the Express and Savanna vans to this motor, and they've been very reliable in those applications. The Silverado LT and Sierra SLE with the 6.6L gas motors are probably the best values in the segment if you don't need all the luxury features that so many new trucks have these days. Dealers seem to actually stock those trim levels sometimes.

    7:02 - perform a dyno comparison between the two engines and you will probably see the 7.3 makes more power at a lower RPM compared to the 6.6
    7:16 - in my experience driving in the rain, especially while trailering, fuel economy typically suffers more than a warm dry day

    Towing with a 24 Silverado 3500 SRW gas. Trailer is a toy hauler, bumper pull, just shy of 36’ long. Empty trailer weight is just shy of 10k lbs and GVWR is 13K lbs. truck does a good job, I would call it adequate. I get about 7.5 mpg towing and 14-15 empty. I don’t tow that often so for 90% of my miles, the gas engine is perfect. Previous truck was a 21 Ram 3500 megacab dually high output towing a 45’ fifth wheel toy hauler with a GVWR of 19,000 lbs and empty weight of about 15,000 lbs. I miss the diesel power and exhaust brake, but I don’t miss the maintenance cost, DEF, higher per gallon fuel cost, concerns about not if but when I’d have an emissions issue. In my opinion, I think the 6.6 gas with a supercharger tuned for torque (not screaming high end HP) would be a really nice option. GM has plenty of supercharger experience on small blocks, they could figure it out. If they did, absolute game changer. I’d think they would sell great for those that need a little more than the base gas engine. The other thought would be to punch this engine out to 7.0 liters, it could use a bit more ummph, that’s my only complaint.

I still turn it on for long down grades, or in town because the engine braking works better, but I see 1 full mpg better running in regular mode vs tow/haul. tow/haul in the ten speed is overkill because of how aggressively it shifts in normal mode in my opinion.

  • @matthewanderson9912
    @matthewanderson9912 8 месяцев назад

    Nice review. I’m not surprised about the fuel mileage. I figured it would be potentially less because it’s going to keep the engine wound up more having more and closer gear ratios.
    You can see where the huge advantage is and that’s the gap between 2nd and 3rd on the 6 speed. It’s a pretty big jump there so I knew your 35-70 mph run would be much better.
    Not sure that the 0-50 will be any better though. Be similar anyways because again, the 6 speed just doesn’t have a good ratio between 2nd and 3rd gear. So 0-60 is fine with the 6 speed but above 60 mph you got a dead spot until you can get some rpm built into 3rd gear.
    The 10 speed has fixed that however obviously.

    I tow a lot but with a half ton 6.2. Wet pavement with standing water makes a massive difference on rolling resistance, there's quite a few wheels on the whole rig. That will affect both mileage and power required to pull that load. This needs to be done again on dry roads.

    • @charlesb4267
      @charlesb4267 8 месяцев назад

      That was my exact thought, the mileage suffered from that wet road, there is a lot of extra drag with truck and trailer tires having to push water out of the way. I was surprised at the performance improvement given the adverse conditions. Hard to control the weather and no doubt limited time/chances to do the test and have access to the truck.

    6:50 I think if it shifted to (7th gear?), it would have dropped RPM to around 2700 which may have been too low for that particular condition. At that specific speed, the 6 speed might have had a better ratio to keep it in the lowest possible rpm for the given load.

I am with you on the diesel emissions problems as I don't need those headaches while towing. I am thinking the Ford 7.3 Godzilla w/10 speed Allison but just caught your 6.6 GM w/10 speed Allison test and it intrigued me. Wondering which one you would prefer if you were buying, I know there's a lot of variables but in general which one would you prefer? If I buy a gas unit I would have to have the 4.30 rear gear to help over come the power loss from my diesel.

    • @GettysGarage
      @GettysGarage  8 месяцев назад +2

      You said exactly why I would go with the Ford . the option of 4.30 gears. these are HD gassers you aren't getting good fuel economy so might as well get the aggressive gearing for increased performance. Also the 7.3L is putting out more power and ford even speculates that the power ratings may be slightly under what the engines are actually putting out. when I pulled with the 7.3L with 3.73 gears I was very impressed.
      myself I drive a 6.4L hemi with 4.10 gears and out of all three trucks the 7.3L has the best towing performance in my opinion.

      Not sure I can agree with you there. GM actually innovates more useful technologies than most any other OEM. Since the new millennium GM's developed, and introduced MRC, (Magnaride Control) 4A (4 wheel auto), composite beds. The multimatic tailgate is the best in the business IMO. The steps in the bumper, and side of the bed are ugly, but extremely useful. I prefer them to the tailgate steps in me and my wife F150's. GM camera systems have been copied by all the truck OEM. GM invented the rearview camera mirror. When talking performance cars with manual transmissions they introduced no-lift shifting, as well as auto-rev matching. They've taking the OHV playform to the next level, and the GEN5 SBC is a very modern engine. (I just wish they'd dump their crappy DOD, and adopt dual port injection) Still GEN3 Coyote even took some que's from the GEN5 SBC in Ford added nodular main caps, they went from 11mm to 12mm head bolts like the GEN5 SBC did from LS in 2014.
      GM is actually a very innovative company that introduces a lot of new technologies that other automakers copy.

      Yes, those 0-30 runs were all done before I hit the highway. And thats fair, I guess its more a personal preference. these hills are pretty lenghy so the truck is going to have to downshift no matter what and I hated seeing the truck just drop speed and lug down before shifting. alot of big semi trucks with automatic transmission will do that to save fuel economy and it we get alot of drivers complaining about it.
