Should Ram have built/ build this?

I'd honestly have it to pull a 5th wheel/gooseneck trailer. The section between the bed and the cab (the storage bit) looks oddly choppy, but having extra cab room plus bed room would be nice. I'd say these things would have sold like crazy had they built them.
Yeah I think ranchers and anyone towing a lot would find them very useful. Hence the name “Long Hauler”
