2003 Titan Avalanche Three Horse

I love this trailer but Im looking to upgrade to a gooseneck. Its been great and Ive never had problems with it. Tires are about three years old with maybe 500-1000 miles on them. Has a place for a battery for electric brakes but Ive never needed them. Theres a little bit of surface rust but nothing that goes close to through the steel. The only issues with it are one of the slants are bent to the shape of a horse because the previous owners horse liked to push against it but its never given us issues, one of the window grates is bent a little bit but still fits just fine with no issues opening or closing it or the window, and right now two of three tie rings on the curb side are off. Again, previously owners horse was a puller so the screws ended up being loose so we removed them before they became lost. But they will be replaced before the trailer is sold. I just wanted to explain why they were missing in the pictures. Its been cleaned for the fall and is ready to go.
