The price is in the ball park of some used units I have seen, depending on the condition, try
www.nadaguides.com and see what you come up with, also run a search on
www.rvtraderonline.com . It won't hurt to try and beat them up for the hitch and whatever else you want. ;D Also I would read the posts on tires, from others experience it looks like a good idea to not run tires over a couple of years old.
