I mean… they can. I drive a Maverick. My bed easily fits a riding mower, a weed eater, pressure washer, pole saw, and all the manual yard tools I could need for working on other people’s yards.

And my wife and children can also comfortably ride in it when I’m using it for family transportation. And I average 43 miles to the gallon.

Not every truck needs a full size bed, and four doors doesn’t make a truck less useful but more.
