Foam cannon mod for holding more washing fluid?

[brondondolon]

Has any one seen or done any mods to their foam cannon to hold more soap? I have a fleet of semi trucks coming up and that little bottle only does enough to do 1 pick up truck. I was thinking of something like the shape of a milk jug. 1 gallon with a handle type of thing. Any one ever seen something like this or know a company that makes plastic jugs?

I saw a picture somewhere of a cannon with a larger bottle. It would only really mean finding a bottle that had the same thread as the one that came with it to actually use more mixture.
