I had a 2005 29.5lktg and enjoyed it. I would make sure it had 50A if possible and a second AC unit. It struggled to maintain a cool temp in hot weather. Really, really make sure the caulking is good because even a little crack on the trim around the bottom walls will cause big problems. Of course, the HHII was not made at the main Hitchhiker facility, it was made down the road and had the lippert frame. It was less expensive.....
It was a good, efficient use of space for it's length and I pulled it all over the place with a 2500HD diesel PU.
