I helped a relative move from CA to WA and I think it was a Ryder truck (forgive my heat stroke memory fade, it might've been a U-haul...). They said it had A/C, but didn't mention it wasn't working on our move day, the hottest day of the year 100 temps OUTSIDE. It started overheating 5hrs into the drive during the hottest time of day, and busiest parts of traffic (of course) had to drive with the heater on full blast to keep it from overheating! I thought it was weird that I drank a 2 liter bottle of 7-up and didn't have to pee the entire 1st day driving. Turns out I don't recall sweating that much either, it pretty much evaporated leaving ashy salt on my skin. It must have been 114 degrees in the cab. It felt like driving with a hair dryer on high blowing at my face most of the time. There were other problems with the truck, but as bad as it was, I dreaded breaking down and having to unload everything on the side of the road in the desert, and reloading into a "good" truck even more. It must've been fate and the stars shined upon us, and we did not break down. The second leg of the trip, it started to rain, and the wipers were crappy and the windshield was cracked and leaked, but after literally driving through hell, we made it. So my advice is check out before hand if all the important things on the truck indeed WORK before heading off on the big adventure.
