Have you checked in with RV RENTALS... I know of folks will rent a RV at their destination and have all their camping fun then get on an airplane to come back home.
I'm sure you can rent just about every type of RV's and get a feel on which one you may like better...
I've never rented one but shouldn't be too hard to find out how all that works...
I have traveled with a friend on a couple of outing in his hugh truck camper. This is one with slide outs and side door entrance and truck was hugh with 4WD etc... There is alot of room inside on of those but it takes a big truck with duallys to haul it all... You also have to pull a util trailer to bring along anything extra.
To me that the big downside for the truck campers - you lose your truck bed to bring along all that extra good stuff you just can;t camp without. The other thing to deal with is what to do when you want to go somewhere after you get everything setup at the camp ground.
