I have'nt seen a CUCV Crew Cab built by GM, but I do have one of the Air Force Dodge 4x4 crew cab trucks. It is not an M880 but is a government contract truck with the stick on data plate on the dash. It is blue with no black out lights and is a short bed. I don't think Dodge built long bed 4x4 crew cabs, because the frames would not be strong enough, but I could be wrong. Chevy had no problem building a long bed 4x4 truck with a weak flexible frame though. I bet they did build a couple of prototype Crew Cab CUCV's for testing and they were rejected by the Military. I have a 4x4 GMC crew cab that was converted by Landoll Corp into a Crash Rescue truck. I'm converting it myself into a camper hauler. It will have CUCV bumpers and brush guard and probably the shelter carrier stuff in the bed too. I won't install any black out lighting, but the lifting shackles will be there.
