I'm looking for my first RV, nice but pre-owned, probably a Class B that I can stand upright in, with a length around 21-23'. The problem is, other than a couple models like the Rialta, and I believe the Roadtrek 210, I'm stumped trying to figure out which models of this size RV are also short enough to fit in my 9 ft. high parking area. Very few ads mention exterior (with a/c) height. It occurred to me that maybe there are only a few makes and models that fit these specific height dimensions, which would narrow my search enormously. If you can help, I'd really appreciate it!
