Water & Fuel Container Storage/Mounting

Hello...curious of the groups opinion for best type/manufacture of water/fuel container storage and mounting. I like the Rotpax concept but seems pricey compared to the original 'Jerry-can' style. My plan is to attach bracket to both sides of my camper-trailer diamond-plate tongue box.
If you use the jerrycan style, there are lots of options, smittybilt sells a cheap carrier. I think the scepter cans will fit in them. I’ve got a couple “desert patrol “ cans by reliance, I ended up doing this

That is 2/3 of a plastic file crate. Fit perfect and I needed a flat bottom to support the weight.
They don’t fit the jerrycan carriers.
