So this discussion raises a question -- where do most people carry gas cans for their generators? If I had a roof rack on my truck, it would go there. If I had an open cargo bed, the can would go there. But my truck has an enclosed cargo bed -- I have one of those camper shell toppers.
So for me, there are only three choices -- in the cargo bed (where the fumes can build up), on the tongue (no room), or very securely mounted, high up on the rear wall of my trailer.
I have opted for the third choice, but I am very aware that the can is vulnerable to a severe rear end collision. The safety concerns expressed by some of the posters above are entirely valid.
