2 wheel dolly?

[CoconutPie84]

It would be cool to have a 2 wheel dolly that several boxes could be stacked up on to move them to the storage area or at least use once you've thrown the boxes from the curb to the storage area. The dolly then could help move multiple boxes to back rows in storage without have to run back and forth or start throwing boxes again (which I do to cut down on running back and forth). Yes, the only challenge would be using the dolly on the steps unless programming could prevent boxes falling off the dolly as it goes down the steps and it wouldn't jam when you need to go back up the steps.
