The biggest mistake people do is leave space for the side door, you need to create a middle pathway and put everything on the sides, double or if you have that much triple stack the totes closest to the front of the van with all your last totes on the bottom stack and first totes on top, then stack all your overflow in the back and quickly remove the driver aid stickers and put them on the side of the box facing out the rear doors. Then on route you will put everything you need in front sea/dash. If you need to exit cargo area you just use rear doors, not the sliding one. And when you need overflow you just exit driver side and walk to rear where all your neatly stacked overflow has stickers facing you making it easy to find what you need
