Great job, I want to do that but only for my rear tie-downs. I have a lot of scrap steel tubing laying around and access to a heavy-duty press (but no welding equipment), so I am wondering if I could just cut a single length of square tube (one for each side of the hitch receiver) inserted and secured in the hitch receiver with a bolt like you did, long enough to protrude to where I want to connect the turnbuckle, and bent slightly at an angle toward the front of the truck. Then instead of welding a plate at the outer end, could I simply drill one hole and attach a heavy-duty quick-link to connect the turnbuckle? Would this work?
