Made another carrier, for good friend Simon. Some changes made from my original. I think I have a much better hatch grabbing arrangement at the bottom. Little forward pressure on the door panel but lots up vertical grip. Tire is very solid to the ladder and the ladder very solid to the hatch. Also I repositioned the tire placement to be about 3″ lower than my original so less intrusion into the rear window.
Having the tire on the hatch is a compromise. You do need to have special hatch struts to make opening the hatch an easy process. Simon has a pair of very beefy 1250 N struts that raise the landed hatch with no effort.
The top hangers and the bottom grabber assembly is made from 0.120″ thick 316 stainless. Bolts are stainless. But the lug nuts and the mounting studs are steel.
I’m going to make some more, with some further refinements.
During the build, comparing tire placement with my original ladder.
