In my work van I have the pack out track system on the floors, tool boxes click into this like Velcro, then I have lights and vacuums that all part of the packout system. When I was at KMS they came out including the Milwaukee rep to look at the van setup. I'll get some pics posted. The entire system works great. You can hit the brakes and everything stays. And if you have to move larger items the stuff all stacks like Legos. I do believe that Milwaukee has that packout system in the bag, and are ahead of Dewalt on that. They sell all three brands, Milwalkee, Dewalt and Makita at KMS, the red stuff seems dominates that store. Lots of different tools.
That is true. My yellow tools are in the red boxes.
Only draw back is you need to I stack them all to open the boxes in the middle or bottom.
