Like boats, I think a person needs about three or four different RVs.
1) a small camp trailer for quick weekend trips
2) a motorhome for long road trips
3) a big 5th wheel for long term stays
4) a truck camper for when you want to drag the boat along
5) a small stinky, leaking, ratted out, no heat or water, $200 camp trailer for relatives to stay in when they visit
