I have taken our 27 footer through heat of all sorts. In 2013 we happened to be in Las Vegas, with outside temps reading 130. Our AC struggled to keep the inside below 100. Part of the adventure. A big part of the west had that kind of heat then, we were in it from Salt Lake City to LA. Last summer, we drove to Florida in August with no heat issues. The point is, it is really hard to plan a trip based on weather. Yes, it will be hot in the South during the summer, and it will be cold here in Western PA in the winter. Will these kind of temps. keep you (or us) from enjoying the RV? To the OP, I would focus the THE purpose of your trip. If you can move from town to town, or certain areas of a town, without the size of the RV being a factor, then the RV might serve you well. However, given you are looking at areas around cities or large towns, a vehicle the size of a car might serve you better. Best wishes for success.
