I went from a truck camper to a 22' 5th wheel to a 30' 5th wheel. After this summer, I'm getting rid of the 30' 5th wheel. It's too damn big to be practical for the type of RVing I like. Haven't used it in some years and *rough it* with my small van instead. The van gets me where I want to go; I cannot take the 5th wheel to those places.
Point being, buy the rig that will suffice for where and how you want to camp. I don't want a towable any longer and will likely get rid of the current van, truck, and 5th wheel for a fully self contained Class B.
