Just started designing a cooler / spare tire carrier for the rear bumper. The posts about failing single shear pivots is leaning me to a double shear with bronze bushings.
I like the design, what cooler box do you use? I've been using 4x4Labs rear bumper for the last 5 years and a lot of abuse and they are still hanging in there well. I stand on the tire frequently to get to the RTT with no issues. Stout.
4plus products are nice, I have 4 to build so were going to build them ourselves. So far I like the Pelican cooler, lifetime warrantee. The little boxes under the cooler are water / gas cans.
