Apples to apples measuring the temperature was harder, time of day, clouds, outside and inside temperatures have to be close before and after.
Doing the air flow mod (it was a mess) at the return made the biggest temperature change, a couple of *'s at the vents with the outside temp going up. We have a dometic ac so the roof coil already has styrofoam insulation.
However
Anytime the outside is going to get over 85 we have a portable ac we place between the front seats, vent out the drive window and powered externally to the 20amp campground.
