We have a 21 foot fifth wheel --about 20 yrs old. We got it thru Craigslist. We have recovered couch and bench seats, new carpet, new toilet and new curtains. DH is constantly doing something to it. LOL. We, too, have a 1/2 ton pickup. We used to own a 36 foot diesel pusher........and HATED it! yes, it had room, but it was such a pain to get into parking spaces, etc. And climbing the stairs up into it just about did my hips in. This 5th wheel has 2 steps....I LOVE it!
Be sure to go to NADA.com and look up any rig you're considering. We almost bought one until we found it weight almost 1000 lbs more than others AND the value was a lot less than the sellers wanted.
