Fixing a Loud A/C Camper With Leftover Foam & HVAC Tape - Budget Air Diverter

The A/C in my camper is annoyingly loud and doesn't cool off the front half very much. I looked into buying a premade air diverter, however it would cost $180 and still need to be customized for this 5th wheel.
Instead I had some time, a half sheet of leftover foam insulation and HVAC tape from an old project. Basically this was free. It might cost you $10 if you needed to buy everything yourself.
The entire project took only a few hours. Most of this was measuring, cutting outside, then cleanup as I was camping still, test fitting, then repeat.
I would definitely do this again if I buy another camper. There was a huge increase in airflow, cooling, and significantly quieter. I no longer have to raise my voice to talk when the air conditioning is running. The front bedroom actually gets cold now too!
My camper is a 2013 Open Range 318RLS 5th wheel with a Dometic Duotherm. Your air diverter design may be a little different than mine. The idea is to split the airflow evenly and smoothly to both air ducts. It doesn't need to be perfect as it's just a loud, leaking turbulent box already and anything is an improvement over that.
Good luck with your design! Leave a comment and let me know how it worked out for you.
