What options does it have? I have a kaufman trailer with the following options: extended 20 foot deck (18 ft deck 2ft dovetail), Diamond plate full deck, removable fenders, 10K jack, 3500# axles both w/brakes, stake pockets and rub rails down the side, spare tire mount w/spare (never touched the ground), 6 welded D-rings into the deck, and slide in/out ramps. What year is the trailer? what kind of shape? I have had my trailer for 18 months now and have put maybe 2500 miles on it if that. Do you have any pics? I gave you the specs for mine to give you an idea of what they cost new. Mine came standard as a wood deck, 18 ft, hard mounted fenders, like a 3500lb jack, smaller axles, and no stake pockets or rub rails. It was around 25-27 hundred w/no options. I think the added options was around $800. Granted steal was alot less a few years ago. Need to look at what it would cost new and then go from there with a decent amount taken off for it being used. Just my .02 Good luck
