That's encouraging, folks, thanks.
The last trip we took before selling that Roadtrek was supposed to be a lengthy Colorado tour. We knew the a/c was inadequate for high temps, but figured Colorado would be a safe choice.
Didn't work out that way. There were record high temperatures all over the state that summer. When we got to Telluride and found we couldn't get the inside temp below 100 degrees, we threw in the towel and went home.
I know Roadtrek has upgraded to higher output RV a/c units since those days, and we'll be looking at RT's again. I just want to make sure that, whatever we end up with, it can handle triple digit temps (which we sometimes can't avoid) adequately, even if not altogether comfortably.
The subject says it all-- we had a bad experience the last time we owned a Class B (1998 Roadtrek 190 Popular), in that the residential-type house air conditioner was almost totally useless if the outside air temperature was over 85 degrees or so. We're now considering buying a Winnebago Era or something similar on a Sprinter chassis, and curious how well the a/c copes.
Since there's virtually no insulation in such units, we're not expecting miracles-- but if anybody has camped in 90 or 100 degree temps, I'm curious if the unit can be made livable with use of all the usual "tricks" (maximizing shade parking, covering windshield and windows with Refectix, etc.)
