Rick,
Rogue removed the carrier from under the truck and he puts his spare in the cargo area for clearance when wheeling. Now he needs the cargo space for a move. His plans are to put it back under the truck but also to improve clearance by raising the spare the maximum amount.

Rogue,
That should work OK for tyre diameters up to 33". Not sure about larger. John Holmaas did something similar and posted pics. There is a lot of verticle room under the cargo floor.
Let me know and I'll try to dig up links to his mods.
