NOLA, I have been thinking of going the same route as you for carrying our bikes on our Grey Wolf. The only thing that concerns me is that it looks like the spare tire will only be 12" or so off the ground, have you had any issues with the spare tire contacting the ground?
I found the fork mounts, but I haven't been able to find the anything to secure the rear tire with, what are you using?
