Rear bumper mount is probably the answer... One can buy a universal mounting rig. I did for my last P30 rig. I just can't see waiting around for hours to have someone change a... tire?! I guess I'm just too darn independant.

anybody know anything about the vigia automatic tire pressure system? Know someone who has one? I went to their website at gio-set.com and found some info but no prices, depending on price it might not be a bad way to go....especially if you win the powerball!!!
