You lucky dog. I was bidding on one of those today. Actually saw it in person.
You got lucky, trailer has some rust, tires look good, but the finish on that cargo top is really nice and smooth.
BRING BOLTS AND NUTS, 3/8 SHOULD BE GOOD or just a bit smaller. The top IS NOT bolted to the bed at all to if driving it off, it may cause a problem with bumps. Look on the inside pic and see how many mounts there are. There are two bolt holes for each and get enough for them.
Again, I saw those today when I got my trailer, as I was high bidder on one for a few days, but it went way past my limit.
But both are in pretty good condition, and they are huge on the inside. almost looks like you can stand and still have room.
You scored!! Good job.
