2006 Nash Travel Trailer

2006 Nash 4 season 23 ft travel trailer. Trailer has 2 owners, first owners never used, so trailer undercarriage is like new, has a few things to fix, everything works, no leaks or structure damage. Needs a good clean. Paid 17000 for trailer in May 2022, asking 7000firm, these are very expensive trailers new. If I fix it raise price to 10000.
