BigB,
When I was in business, I had 4 trucks and each truck was set up the same way. We kept all the boxes in "milk crates" (the ones that you can buy) and kept them on the bottom of the wood shelves. (1 truck had metal shelves) The wood in front of them prevented the crates from sliding out from under the shelves. 1 crate had the "rough in" styles, 1 crate had old work, and one had utility and 4" sq (1900) type of boxes. We only kept a few of each style on the truck. If we were roughing in a house, then we would bring cases of what we needed. The ones in the crate where just "Stock" in case you were on a job and needed something extra to get a job done.
