I have some old NATO cans that I refurbished that I like. The problem I have is that the spouts I have for them leak more than the CARB spouts, if that's possible.

I like plastic cans more than steel for durability and weight. I just can't find any that I like for their size.

My rig has a liftgate. I don't think I can make a swing-arm work there. The other possibility is a roof rack.
