If you get some extra time, could you take some pics of the back side of the rear arb bumper? Curious how it's mounted to the frame. Are the bumper wings very robust? Do they look like you could jack the truck up by them?Here is what I believe is Steve's ARB P#s for the bumper configuration he has:
Bumper itself:
Rear Bumper- 5611210
LHS tire carrier- 5711231
RHS tire carrier- 5711232
Hilift mount/ license plate holder:
HILIFT Mount for Wheel Carrier- 5700060
An optional barri nut and socket is available to secure the jack to the carrier. Part number, 6151334 (not clear if Steve has this, but I think its a security option)
