Thanks everyone for your quick replies and assurances. I suppose it might help if I provided a few more details.
First, I'm looking for something in the 22-24 foot range, & under 3500 lbs dry weight. My SUV is rated for 5000 lbs. I expect I will be the sole occupant most, if not all, of the time. Other than clothes and food I don't expect to be carrying anything really heavy in the TT. I've been considering this for quite some time and have a pretty good idea of what features I consider "essential."
I consider myself pretty experienced in non-mechanical maintenance and repairs and somewhat limited on the mechanical side when it comes to actual repairs.
Where is the best place to get an idea of any particular TT's current used market value?
