While I think it would be a blast to have a truck with fabric come around, and would be more fun to actually drive it, but i think the money for gas and insurance would eat up a lot of profit, and i would question of whether it would turn over enough to keep a fresh selection whenever the truck came around, or whether you could even carry enough variety so that folks would have a good selection of fabrics. Like I say, sounds like a lot of fun, but be sure you do some research first.
