Glad to here you found a hitch carrier that works! How about sharing the Manufacturer, and Model and source? I have tried a couple of models that mount on the bumper and they are too flimsy or just plain small to take the 8 bolt Chevy Wheel and LT225/75R16 Grabber tire. I have seen Roadmaster hitch mounted tire carriers but they want $800 Canadian and would have to special order the beast.
