Diemaster - well you made there and back. That part is good. Relative to your issues I'd recommend you come back here and ask questions about how to deal with the things that went wrong. Most of us would have told you to run your generator and turn on the house ACs while your in such heat. We'd also give you a way to discriminate before you go with things like campgrounds, road side facilities, fueling up, etc. Some folks plan more than others. We are in the plan the trip, plan the trip, plan the trip category. When we have our grandkids on board (a couple of months each), it is my responsibility to make sure we are comfortable and safe. I look for stops that fit my criteria (steady 50 AMPs, good water pressure, sewer and with the grands - a pool). I also plan my fuel stops, routes (sometimes taking the long way to avoid steep, windy roads) and overall scenery.
Coming here you can begin to avoid most surprises.
