tjkj: Im assuming you cut the plastic lip so that drawer can come out. Pretty neat!
Here is my setup:

I have a Husky toolbox, and craftsman bag as well as tools on the cargo shelf and bellow. I dont have the box bolted down or even strapped and it doesn’t move or shift at all. Works quite well as I find myself working out of the back of the jeep quite often. Kinda messy, hopefully Ill get some time this week to organize and detail the indies of the jeep before my trip.
