What I'd like to get an opinion, or several, is could I mount the tire on the rear bumber as I have seen others do? What are the drawbacks other than looks? Also, anyone know where I can find a tire cover made of aluminum?
Based upon the experience with my '64 Overlander, I would definitely advise AGAINST adding the spare tire carrier to the rear bumper. My Overlander had its spare tire mounted on the rear bumper for much of its life - - the result was rear end separation and repair expenses of just under $2,000. I detest having to carry the spare in the tow vehicle, but at least for the time being, that is where I carry the spare for the Overlander (there is insufficient room for the front tongue mount with 40 pound LP tanks).
Beyond the potential of contributing to the development of rear end separation, I would also avoid the rear bumper position on a single axle coach to avoid subtracting weight from the hitch.
With my Overlander, the plan is to have one of the modern, under-coach mount spare tire carriers adapted for the purpose. I kept my 20 pound LP tanks on the Minuet so that I could add the behind-the-tanks spare tire mount when I have the exterior restored (the Minuets used a very similar spare tire mount to the one found on your GT).
Good luck with your research!
