Before the end of the summer I'll decide which one wins and put it into action, thinking I'll need it to get the A-B-A tests done.

The other advantage of the "captured hinge" is that you can leave the receiver uprights in place, and build other things to hook into it (bike carrier, etc). The most difficult part of the whole hinge setup is finding tubing of the right sizes, but you could just use 90deg angle for the "outer tubing", since it is just there for the smaller tubing to rest on, but a proper half-pipe would give more bearing surface and less wear.
You can place the 3 pieces of smaller tubing, run the pin through them, spotweld the outer 2 pieces in place, lift out the center piece that is mounted in the carrier upright, place the tubing group into the receiver uprights through the slots, spotweld everything, then cut out the outer tubing from the gap between the uprights. Then put the carrier upright between the receiver uprights, run a center punch through the hinge tubes on the receiver uprights to mark the carrier upright. Drill the carrier upright, run the small tubing through it, tack it, and check everything before final welding. Total time, probably an hour or less.
