They're out there, just gotta pay attention to the length of the draw bar on the rack. I've put a Trials bike on mine and I'm pretty sure my 426 will fit on the JK, too. Spare is a 315/70-17 on TF carrier. Hitch receiver is factory.
Their products have a pdf file showing dimensions. I have the Cam-loc JH05, heavy duty, about 80lbs. Hitch pin to center of bike's track is 24". Doesn't rattle, barely moves, but you can sure feel a bike hangin' out there on anything other than a truck when hittin' turns on gravel roads at pace. Plenty of clearance with the Trials bike, the tailgate is down on the truck pic and I have plenty enough clearance. The bikes tie down solidly with the wide-spaced tie mounts. Have had my Joehauler for 15 years. If I need it to haul my heaviest streetbike, it will. It wasn' cheap then, it really ain't cheap now.
You can find carriers for under $200, but I don't entrust my possessions to Chinese support...there is always an issue with cheap that may put your valuables at risk.
