Look, I'm 71 and tow a large (40') 5th wheel. If you're just planning on weekend camping, it probably doesn't matter whether you get a 5'er or a tt. Although I watched my S-I-L hook-up his tt with the weight distributing hitch, and no thanks. Now if you are planning on snow birding or staying longer in the unit, I'd have to say a 5'er fills the bill better. Others may disagree, but that's my opinion, after over 40 years of camping. The 5'ers tow well, are easier to hitch (IMHO), and generally have more storage space. But more importantly, you need to consider the type of camping you are going to do, and the features and floorplan of the unit you are considering. I've seen some beautiful units that have no counter space, limited storage and uncomfortable living arrangements, like tv in odd location from the seating, or only a couch or dinette to sit at. If you are thinking about moving to full-timing at some point, you are going to need to take a lot of stuff with you and will need more storage. Where do you keep canned good or spices and such? Do you consider having company, or are you claustrophobic? If so you may want to consider slide-outs to give you more floor space. Do you have a cat? where are you going to put a litter pan? Stuff like that all should be considered.
