We've stayed at quite a few truck stops (Flying J, Pilot) and Walmarts, and I'd stay at the latter over the former any time. Truck stops are noisy beyond belief, although no one will complain about running a generator in your truck bed for the AC. Walmarts have been our choice for overnights since they're usually close to the road we're traveling on so easy in and easy out. Like someone else said, we can cook & shower on battery & propane with no difficulty. If it's hot, I keep a $300 Harbor Freight 4kw peak generator in the truck bed and it'll run the AC all night on one tank. Only issue we've ever had is finding a spot that's fairly level.
