I have the rockrover bumper with a custom swinging built by Rob's minions. Later modified by us to include gas/water cans and lowered to allow the rear tailgate to open without hitting the tire. My biggest gripe is losing the tow hitch, but I may try and put an original hitch on and cutting the rear skid plate to allow access. That being said, I don't tow with my p38 but would like the option.
I bought the ruffstuff large swing out joint and then it was welded to the swing out arm we made. Fairly robust.
If bearmach makes a metal rear bumper, then you can have a swing out arm made and use the ruffstuff pivot. Ruffstuff is located in Loomis by us and makes some crazy serious rock crawlers. CaliFab hereally is Sac could do the work. We can call him up, he was at the pub with us in September.
