If the OP really wants to consider living there he should experience the heat for himself.
One step outside of ANY air-conditioned building is enough for me to say "nope, not for me!". I don't need the RV to tell me that! I truly don't think you'd get a much better feel for living there if you spend time staying in an air-conditioned RV vs. an air-conditioned hotel room.
Then your vehicle has a cooling issue
Not necessarily. I have had perfectly healthy vehicles have this problem in extreme conditions.
Regardless what you decide, don't let the (incorrect) comments about RV traveling in the South
Sorry, but experience has dictated these comments are not incorrect. I have traveled many times through the DC area in multiple vehicle types. On multiple occasions due to extreme heat and extreme traffic with perfectly fine vehicles it has been necessary to shut down the a/c to avoid the engine overheating. If there's a TT or 5'er involved a generator is totally irrelevant.
