The frame and axle look the same as my m101 3/4 ton trailer, with a different bed. The axle, d-rings, and 2" wide springs are from the m101 series. The m101's were made to pull behind a 3/4 ton truck, I.E. Power Wagon. We had several we used with our Hummers. I have one with a normal bed, and it pulls fine behind my heep. The only concern is they don't have trailer brakes. They only come with a parking brake. If you can find one, it would be a cool trailer. If not, build one on a pickup frame.
