Yeah, the NATO cans I have take friction-fit spouts.I have them in storage at my in-law's house (They were very dark gray, not OD, by the way- German, I think). I should go pick them up now that I have my own house and outdoor storage.

I don't know about the shelf life of gasoline in a steel versus a plastic can. Than's an interesting point that bears further investigation. I imagine that one would ideally rotate fuel in either type of can before it became an issue.

I am liking the Roto-pak cans for my rig. There are a few 4x4 outfitters in town. I'll have to stop by and see what they recommend for attachments (swing gate and roof rack).

If anyone has pictures post some up. Someone here must have fuel storage onboard their truck or SUV. It's the nature of the board and all.
