plastic gas can protection?

Hi folks,

I'm wondering if anyone's handled this problem already and has an easy solution? I have two treasured five gallon gas jugs, the old fashioned kind before the government made them all complicated and expensive. I'd like to bring them along on a long trip I'm planning to take, as emergency fuel for my TV and fuel for a generator. I want to carry them safely and protect them from rocks and road debris.

My TV is a station wagon, so there's no truck bed to stick them in, and I don't want gasoline on the roof rack, so that leaves the A frame / tongue of the TT.

I will be deleting the battery that lives on the a-frame, so there's quite a bit of space there in front of the diamond plate front wall of the tt, and behind the propane tank. I was looking for some sort of tall and skinny metal boxes that I could bolt onto the a-frame, that the fuel jugs can slide into.

I'm thinking I can cobble something together from aluminum diamond plate sheet and some aluminum angle section, but if there's a pre-made solution, I'm all for that!
