I have a four drawer about 9 " deep. I use a hand truck that folds flat if I must travel much distance. Tried the 3 drawer. I just can't get enough in it. Whole thing weighs 45 to 50 pounds. As far as a for a van, do not, I repeat, do not get the ball bearing slides. All the drawers will roll open if it is not latched. I had a big Craftsman with ball bearing slides, and had to replace the slides constantly. On other hand, my toolboxes with the regular slides have been going for 30 years with no slides replaced. One is a Craftsman, and one is a Snap on.
