I need a tire carrier! The bumper swingouts are heavy, expensive and inconvenient. Hitch mount options stick out a long way and reduce departure angle. I hear the door-mount ones are a lot of stress on the thin sheet metal and seem fragile. It sounds like the ideal solution is an external swingout cage that mounts to the factory door mounts. It could even be cleverly designed to open with the door. Why doesn't something like this exist? In the mean time...what's the best option out there?
