Not actually having had an RV, I'm going on the kvetching I hear here. Getting them clean sucks, using the water up too fast and/or getting them pumped, generator issues, driving them safely if you've never handled something that size ... and so forth. But you're not a first timer, so you know the drill, and you know your camp mates. different situation.
We do fine with our little tent under a carport. I even have asthma and I do okay. All a matter of personal preference. Just sayin' a first timer in an RV may not be the best choice without a veteran they know and get along with on board.
I'm too jaded to think up a good sig-line. Need more coffee.
