Probably because the "availables" didn't have rear fenders and the "not availables" did.
Bill -- That could very well be the case. I have seen two earlier MY 1-tons (see pics below) that were duallie pickups. The '46 is owned by Jim Carter and is a beautiful restoration. It is very factory.
Not sure about the '38. It appears to be a factory job and missing its fender extensions.
I have never seen, smelt nor heard of an AD factory 1-ton Duallie. The data book would tell us that they were not made.

The Jim Carter truck MAY be factory, but the fit and finish on the '38 has me doubting that it came from the factory. Would the factory have put "tubs" on the inside of the bed?
No particular knowledge on my part, just an opinion.
'57 GMC 102, Original 347 V8, HydraMatic, 3.08 rear gear, added A/C, disk front brakes, HEI, AFB carb, '98 Honda Black Currant paint. T-boned and totaled 10/13 '52 GMC 152 Stake Bed, Original 228, SM420, added A/C, disk front brakes, '67 Chev 3.55 rear gear. Gets used as a real truck.
Pulled the "hub cap" off one of my front wheels today at the show and grabbed a shot of the actual hub cap. the 3804's (or any of the SRW 1-tons) have the press in cap.
