If I was an eccentric billionaire, this thing would be my ride.
Like, just the cab. I wouldn’t attach a trailer to it or anything; I’d just zooma-zoom around town in that cab. I mean, look at it:

Doesn’t that just look like something I’d drive around in? That freaking windshield wiper propeller is so totally me.
Edit: if I was an eccentric billionaire, I’d actually probably still walk everywhere. I’d drive this to go get groceries every week or something.
Edit 2: I could attach a trailer, fill the trailer with groceries, and then drop off the groceries to like homeless shelters and stuff.
