Re:1993 Chevrolet P30 Food Truck Build
Actually many places allow trucks to be fully self-sufficent wherein there is little to no need to visit a commissary. As long as you have a legitimate place to get fresh water and to dump waste water (and, like you said have proper hoses and storage) then you will never need to visit a commissary. As long as your state allows that (self sufficient). Appropriate places to get water could be RV parks, marinas with dockage, a church, commercial kitchen, etc. And I'd love to find a free one...but that sure as hell doesn't happen down here!
