Winch with box on wheels inside vault

[CyberBC]

I was looking at the picture of the Cybertuck with the end gate down this morning, and I thought what if i built a box the size of the vault bed on wheels and used a winch at the front of the box (or bed) to run the box up and down from the truck bed to the ground. For camping it would bring all the gear out and make it accessible for the night and free up the vault for sleeping. I imagine contractors would also like the accessibility. Thoughts?
