That hitch and rig were originally mine,
sold it to Blair when we bought the 07C19SD. I had the hitch made by Huntsville Steel in Huntsville, TX. It was a good thing from the git-go and with the Shocker Air hitch changed the whole feel of towing the 5vr. It was interesting to watch the 'bobbing' that the trailer was doing and never feel a thing in the cab.
Hi Taylor, welcome back from sea duty - hope the tailgate works for you.
Pete - before doing the welding we (Huntsville Steel and I) did speak with the Toyota regional rep and a few days later he got back to us and told us that nobody would say it was OK to weld but then again no one said not too. (Must be a legal liability thing.) I agree with you that it would be better to mount the S hooks from the bottom rather than from the top as show in the photo. I always crossed the chains while thinking there really was no 'tongue' to catch - old habit, I guess.
Those photos are posted on Flickr with my other mods.
