I bought a Rotopax gas can identical to this one
http://www.rotopax.com/2-Gallon-Gasoline.html last summer for my trip to Alaska. I took it with me there and back, but fortunately I never used it. It has some road grime on it, and shows a few marks from being strapped to the bike, but otherwise it is new.
This 'can' is quite neat. Since it is so flat, you can lay it on pillion, and stack whatever on top of it. I talked to a guy on the road who HAD used his, and he says his didn't leak a drop. I can't vouch, I didn't use it, but I sure love the slim profile of it.
They sell for 59.99 new, I'm asking 50, and I'll pay shipping.
Please call or email! Oh yeah, I'm in St. Louis, that's Central time
