Uhaul said that at first online also. But they inspected it and My D40 is rated at 6300lbs, 2wd v6. Trailer is 2300 empty. The surge brakes on these uhaul trailers are awesome. My truck has electric trailer brake controller.
Thanks for the ebay find. I am focused on trying to get it on the road for a rolling restoration. Missing, hard fuel line, carb, rear brake hardware, tail lights, body mounts, seat belts. Just some minor things to pass inspection. I only have it titled in my name for now. Now registration without an inspection.
