I built my own years ago. I used 5” C-Channel steel. It worked, but it always scared me as far as the warm fuzzy feeling of knowing if my bike was secured or not.
The first time I used it (in the hitch on the back of my 5th wheel camper) I used an excess of tie down straps. (Like, a dozen, including the ones that went from the carrier to the trailer too). I didn’t want to lose the bike on the way down to Moab.
Being steel it was heavy and slightly awkward to maneuver into a receiver. I’m sure a storebought one with aluminum would of course be lighter.
