I just sold my 1999 Spirit Deluxe. It was originally the model that had captains chairs but at some point (I'm the 4th owner) was converted to the Spirit floorplan.
My trailer was in good shape (for a 21 year old unit), but didn't look new by any means . . . no solar
. . . A/C was a window unit installed in the front lower corner . . . year old tires
. . . two year old converter . . . well maintained . . .sold it for $12,700 to the first looker and I'm sure I could have got more if I'd wanted to push the price.
Hope this helps.
