I was never happy with my Aluminess rear swing outs. They loosened over time, and finally the spare tire carrier failed.
I hoped to make it a simple bolt on procedure--didn't work out that way:
I made two 90 degree brackets that support the shafts Rock Slide engineering uses on their Jeep swing outs.
The brackets are made from extremely strong 2"x.250" steel square tubing, and bolt to the frame of the van and to the Aluminess bumper which, itself, is very rigid and well made.
I copied RSE's design for the swingouts. They are made from 2x4"x.120" steel tubing.
The video says it all:
I'm very happy with the result. They have a much cleaner look than stock. Still need to make a few adjustments however--the EZ Rack on the right side will touch the taillight if not careful. And even though the rear doors have been reinforced with steel plate, they are still flexing too much for my taste. Gonna give them a bit of a test in the Maze next week!
