Here is a list of some of the things you may want to keep on your truck. If you get the plastic tubs from Wal-Mart, ask Thomas for an old load lock. Place it about 4 or 5 slots from the front. You can put the plastic tubs on the load lock and lean them towards the front wall. They will not fall off. we have four of them and our shop vac up front and nothing has ever fell off.
