Has anyone built/bought a rear bumper with a swing out tire carrier? How well does the tube support the weight of the tire and carrier. Changing bumper designs from square to round tube. My existing rear bumper is 2x6 square base w/ a rockstomper hinge. The new bumper base will be 1.5 round .120 wall. I just need to get an idea that will work to support the swing out when fully open. Needs to be strong enough to support a 37" Goodyear. Here's apic of the front almost done.................. So the rear will look something similiar.
