For me, having a permanent bed cover means it's not useful as a truck.

It also has a recommended cargo weight of 6,000 pounds, so it can haul a ton (literally! and two more!) of shit.
This is really no less of a truck than a Ford Bronco or Dodge Ramcharger.
Even so, though - there are plenty of consumer pickup models which are used commercially, and more than a few can handle some pretty big loads (especially towing)...
