This is where the 70-Series shows its true strength as a heavy duty vehicle. There are lots of pickups out there that are a similar size, but few to none would be able to carry the payload or take the stresses of a gun like that.
I’m curious about the second option on the list: a SWB with a 4.0 diesel? Would that be a 2H? I wasn’t aware that SWB and MWB 70’s came with 6-cyl diesels until 1990 with the 1HZ.
