Backstory: one of our dogs is a dachshund/chihuahua mix and, like most dachshunds, has some hereditary back issues... and he had to get surgery :( The good news is he is recovering very well, the bad news is that I'm going to have to sell my trailer to pay off the surgery. I bought it new in late 2012 in OK (the trailer, not the dog), towed my STi to NC with it, and the only other major trip was this year to tow the STi to a track event at Atlanta Motorsports Park. So that along with a few in-town towings and I'd estimate total mileage to be around 2,500 or so. It's in practically-new condition.
It's a 20-ft trailer with an 86" width (I can't remember if that's the platform or fender-to-fender). The lights all work and are LEDs, it has two ramps stored behind the flaps in the rear, and a hand-crank nosewheel. The fenders on both sides are removable with three "Jeep hood"-style hold-downs for door access when loading, and there are four swivel tie-downs (two on each end). Tires are in excellent shape with plenty of tread left. Some minor surface rust on the license plate holder and the hitch area, nothing that a wire brush/sandpaper and WD40 wouldn't fix but I'm out of the country at the moment and my wife isn't very mechanically inclined. It has electric brakes which work great (you'll need a controller on your tow vehicle). Its overall weight is listed as 1350 lbs so it pulls very well, my wife's Trailblazer has no problem pulling this with my STi loaded on it. Comes with four ratchet straps and four "loop" straps (for strapping a car down by axle/suspension/etc if no hooks are reachable).
Asking $5500 negotiable. Trailer is located in Jacksonville, NC. Email me at jj1013@gmail.com since I don't have time to get on the forums very often.
