I have not tried setting the thermostat lower because right now my concern is not comfort but rather in dehumidifying the coach to prevent mold, mildew and odors between trips.
There is a little more to it than just the delta. Insulation is a big factor and we all know most are not insulated very well. Whether you are parked in shade. If you were able to maintain 70 with outside temp of 100 with one 13.5 K AC you must have one heck of an insulation package or the inside is so full of cabinets, walls, and other stuff the the square footage is low. I have a 42' 5th wheel with 3 AC units and it won't do that. Also, 80 is very uncomfortable to me.
