I agree that they probably don't serve most people well.

But I know someone that has a huge truck with a cap on his bed (google "pickup truck bed cap" or "topper"). That solves the weather problem and makes you wonder why you don't see more trucks covered up. The answer is obviously it looks less cool and doesn't fit the image. But it serves him well because he works in construction and frequently has the bed full of materials, sometimes which are longer than the bed. And he uses the truck occasionally to tow trailers.

But he's not most people. And he has another car for getting around town when he's not working.
