Hi Mike,
We have yet to camp in 95 degree weather. But I believe our no-slideout rig along with the thermal windows makes some difference because we noticed our rig stays quite warm in cold weather. The worst of the cold (and I assume summer heat) comes from the cab area. As you have read from other owners, there are some common sense practices that help in hot weather camping.
- yes, the thermal windows (I really like our thermal windows for temperature control and sound deadening)
- yes, a slide out leaks some amount of air, and I think (but uncertain) is not as well insulated.
- equip your rig with window awnings and use them to prevent direct sunlight on your glass.
- buy one of those expensive shade thingys that you place outside over the windshield. We don't own one of those.
- van side window shades of the same brand and general design.
A 2350 no-slide does not have a lot of cubic feet to cool. I think you will do fine. I say this because at home last summer, I did run our a/c once in 100 degree heat for 3 hours straight. Our 2350 was parked outside a few weeks for a garage sale. We didn't stay in the rig so we didn't generate heat inside. I was just exercising the a/c unit & generator and to draw out humidity. It seemed exceptionally cold inside. But coming in out of 100 degree heat can be misleading. I set the thermostat all the way so it wouldn't shut off.
A lot has to do with how often you open the door, cook, etc.
I cannot imagine having two a/c units on top of such a tiny rig. Just ask the factory for the highest outut unit. With two a/c units, you will require 50 amp service which throws the rig wiring into a different category. I think the cost of the a/c and such wiring will become economically impractical.
