Nicholas,
I think you might find that people probably have different goals in mine when they chose a certain type of RV. I'm sure there are some over lapping goals. but also some significant differences.
I've had small travel trailers, large travel trailers, and class c's. Now I have a truck camper. At this point my wife and I want to spend as much time in nature as possible away from the crowded camp grounds. Some people love the social part which can be a lot of fun. But our jobs keep us very socialized so we really appreciate just looking at and experiencing nature. We also have decided to keep it simple. No holding tanks, no built in gas or electric appliances. Last we wanted something that is easy to maintain, load and un-load and some what "greener than a class A. We love the little truck camper more than all the other RV's we have owned. Now if I become a full timer that's another type of RV and social experience. So maybe if you could generally determine what a RV'ers goals are you might be able to set up some type of "RV structure". Truck camper, back to nature goals to the the over the top class full timers. I know there are some full timer's that have full time jobs working from there RV's thanks to modern technology.
Sounds like an interesting project. Good luck, have fun and I hope this is some good food for thought!
