Seems like this thread has been hijacked and is now about "what qualifies as camping?" instead of the OP's original question which was:
"....Is there really little reason to have an RV if you don't want to dedicate your vacation time to camping? How many still fly and stay at nice hotels or do you spend every vacation night in a roadside RV park, night time parking lot, and a campground when you get there?...."
I think the OP wants to know how many people feel that since they invested in an RV, they now have to use it for every vacation?
