I used a boat trailer. After removing the runners for the boat the frame was flat. I turned the bed over and set the frame on it then welded them together. It even tilts. I had to shorten the tongue some but you don't want it really short. The shorter the tongue the harder to back up. Be sure to use a trailer that accepts large wheels. It'll look goofy on 12" tires.
