This trailer is around 3x5 feet. It is a great trailer for pulling behind a car or van, it is compact and tows perfect. I pulled it behind my Pontiac Grand Prix, it dropped a mile or 2 per gal. Much better than on top! It has high speed bearings on so it's made to last. The topper is mounted so you can take it off by pulling out 4 cotter pins. As you can see it is a sears topper, with 18 cu. ft of space. I have one key that locks both the side locks. Also has a spare tire. It takes a 2" ball to pull it. It takes a 4 flat plug for trailer lights, which wiring and lights are all good. It has a stand that removes so the tongue doesn't set in the dirt during storage. If you have any questions call me at 785-299-0522.
