Ok folks, I still need some help. After doing some measuring of the bumper and frame rails, adding a hitch is harder than I thought it would be. The distance between the frame rails is exactly 6 feet. The rails are I-beam and this is inside edge to inside edge. There are two 6" pieces of 2" square tube that connects the bumper to the frame rails. This is all welded.
So with the space between the rails, it looks like my options are to go with this one below and attached to those two 6" pieces of square tube. I think i would need to fully weld all of this, both the bumper attachments and this receiver. then potentially add bolts too just in case. The hard part is I don't even know if the actual receiver tube will go below the bumper. The bumper is 6"X3"
So the other option is the one suggested previously. Weld this to the bottom of the bumper, weld/bolt the bumper supports to the frame much better and call it a day. Thoughts?
