Maybe on a Supercab frame?
Gary, my bet is that this is a cab and chassis truck to start with. A Supercab wheelbase is close but just a tad short, and there were not very many F350 DRW Supercabs. If you notice, the DRW also looks pretty narrow, wheels seem recessed within the flares. This is consistent with the narrower cab and chassis frame. A lot of guys make a DRW with a CnC rear axle, tub the bed and only need to add small off-road style fender flares in the rear instead of the big fiberglass ones. Here is another 10' conversion, look at the rear wheels inside the fenders:
SHORT BED 4-DOOR DIESEL: 1986 F350 4x4 under construction-- 7.3 IDIT ZF5+GVOD
STRAIGHT SIX 4X4: 1981 F150 2wd to 4x4-- 300 I6 close ratio diesel T19, hydroboost brakes, Saginaw steering
BIG F: 1995 F-Superduty under construction— converting to 6.9L IDI diesel ZF5+DNE2
