Yes you got it Blue Steel .... that's the one of many great ideas we can expect in Reveal #2 maybe even a Lumber Rack option that is air operated and can be deployed up to above the top of the truck for hauling Lumber,pipe ,rebar etc.
Cybertruck ideas.... somewhere I got the impression that it might have tool boxes on the sides ? That would be much better for contractors . Also as suggested before a Refrigerator or even a freezer could be used by the hunters who transport the kill they have shot back to the home freezer...
Old Tesla fans will tell you that witch looks like a motor is actually a inverter and power control unit that is round like the motor . This might be where the confusion is coming from ? Tesla kills in power efficiency because they keep wires short and locations close.
