tarbe-
I've been contemplating this idea also. If I can get a plate fabbed up to hold 2 5 gall jerry cans and use the spare tire winch to hoist it up, that would be killer!
I have been toying in my head with the idea of making some sort of drop down skid plate type door that would go from frame rail to frame rail and hold a couple of cans up in the space where the factory spare tire mount is. It would be hinged in the front and the cans would be secured to the plate so they could not move and bang around. I think you'd want to stick with only the best sealing cans because I envision they would be on their sides.
