38 ft Gooseneck spread axle, 30 feet on the floor. Huge side door. I bought this trailer new and have only used it a few times. I had the entire interior finished out with white aluminum skin and the walls are fully insulated. I also had a wench installed and full e-track installed on the entire length of the floor of the trailer and also up on the gooseneck area to strap down cargo. Comes with the spare tire. Everything works and this is a very very nice trailer. I spent over $9,000 in upgrades after buying the trailer new. This trailer is in perfect condition.
