Some more progress as I move along. It is almost finished now
The hitch in the carrier is for a bike rack, or other hitch mounted rack that would be a pain to deal with if it was in the bumper hitch. Most of the time it will have a cap in it. I will build a rack that bolts into it for jerry cans as well, so that I can carry gas.
I braced the tire mount and the main hoop some more. The tire mount now has tube welded behind the plate as well, so that the entire structure is fully welded to the main hoop.
Lastly, I upgraded my latch to a 2k lb one from McMaster Carr, as well as I got the option for a secondary latch to keep the handle from rattling open on washboard roads.
