Will this slide around in my trunk while driving?

Depends on your trunk bed texture and how you load it. The organizer sits on the floor but isn't strapped down — test-fit it before committing. Non-slip matting underneath helps if movement is an issue.

Can I stack things on top of it while it's set up?

The hard panels can take modest weight, but don't treat it like a rigid trunk divider. Heavy stacking may stress the frame or cause the organizer to shift. Use it for medium-weight tools and supplies.

What do I need to do before I use it?

Inspect the seams and folding hinges when it arrives. Wipe down the panels if needed. No prep or assembly required — unfold it and load it up.
