Question on fuel tank relocation

[harshard]

I have seen that a lot guys are relocating the fuel tank where the spare tire fits. I like the idea of relocation but what do you do with the spare tire? Do you just put it in the back of the truck where it can flop around or does someone make a bracket to hold the rim & tire? Just wondering , planing on doing the swap in the near future but do not like the idea of the spare tire being loose in the bed for someone to steel.Thanks, Shawn
