If you end up going with the 30'+ Class watch your payload. Most of the larger C's, especially the ones with slide{s} and levelers come up very short of payload. You will want at least 1,500# and not many larger C's can give you that.
As noted the close quarter handling of any C over 30' can be a serious challenge.
Our 24' C is a dream to drive, fits into any site and makes for a fine grocery getter or sightseeing platform. The large, slideless floorplan works very well for us but we are usually just two and though we can do 4 it is a crowd.
