My guess is that it was a cab/chassis model that had a camper/motorhome on it. Someone took it off and then swapped cabs since the back of the cab was cut open. I like the look, especially with the widened tubs in the back. You can verify if the cab vin matches the frame vin, the frame has the last few numbers of the vin on the drivers side top of the frame right behind the motor mounts
