I said I was wondering if there's a functionality issue, but it seems to be just looks.

Have you ever seen a plumbing truck loaded up?

It's the definition of gypsy wagon.

This is a pretty good example, although a lot of people make their own.

They also take 12" to 24" PVC pipe and put them on top, then stuff them full of conduit; something that the Cybertruck won't be able to do because of the shape. It also won't be able to fit a standard slide, because the bed is such an odd shape.

Here's another example.

By making the Cybertruck where you can't buy it without a bed, in a cab and bed only configuration, it's going to severely limit the commercial market.

People who own a business buy the "chassis cab" and then the bed; they are two separate things.

This is how you get F250 / F350 work trucks for your small business needs; guaranteed that Ford is working to address this market if Tesla is going to ignore it.
