That Trail'd can is a cool idea. Their site says in a few places that their cans are for water, not fuel, though that may be an EPA thing rather than a materials thing. That said, I'd be a little nervous about suspending twelve gallons of gasoline over the road in a container it's not supposed to be in by a single chain hooked to a twenty-year-old hoist designed to raise and lower a spare tire. A secondary strap or even a skid plate to catch it if it falls would make me feel a lot better about it. And, yeah, accessing those in wet weather would not be a good time, though I don't imagine you get much of that in AZ. If you're planning to use the extra fuel often, I would consider mounting a permanent tank in that space instead. You might find a writeup somewhere like Expedition Portal, or wherever the Cannonball guys hang out. You might look at how Ford did it, too--they built a lot of dual-tank trucks, and I'm told some of them even worked right. Trouble is, the dual-tanks I've seen have a second filler neck, and I'm guessing you'd rather not attack your quarter panel with a hole saw. There's probably a way around this. Whether it's less work than fetching cans from under the truck, I don't know. Whichever method you go with, I would come up with a heat shield between the fuel tank and the muffler, and consider installing a trailer hitch (if you don't have one already) to protect the fuel tank from a rear-end collision. I doubt the unibody was designed to protect the spare tire the way it would've been to protect a fuel tank. I'll bet the tank off one of those oilless pancake compressors would fit in there real nice.
