Looks like a Rockslide Engineering "Ridged-Rack"

They also have one that straps to the spare tire directly that allows three mount points (left, top, right) that looks pretty good.
While that looks to be very close, it isn't. That is the Exp One Rear Bumper w/ Tire Carrier. They are suppose to be coming out with that Jerry Can mount in another month or so. I just installed that bumper and want the attachment so I was hoping to get some up close pictures of how they are mounting it.
Cool, thanks for the correction. I'll bee looking at that too. I was on the fence with the other one, it looks like it attached to the spare itself, I'd rather have a more secure connection than a ratchet strap...
