Has anyone ever thought of putting the spare on top of the bus? I'm not saying to just throw it up there but build something to make it match what's already up there. Something low profile that would go along with the air conditioners or satellite dome. I know it would be a pain but so would it be looking for one when your broke down. I know all my bays are full and so is the back of my Tahoe with all the grandkids living out of state.
