He says that 4.10 is the only available option with the 4x4.

He's wrong, unless your definition of 4x4 includes limited slip rear end or the FX4 Off Road pkg.
The F-350 DRW 4x4 can be ordered either with a 3.73 open axle, or a 4.10 limited slip rear axle.
The FX4 pkg requires limited slip, so that rules out the 3.73 ratio in combo with the FX4 pkg.
Surf to
www.sunrisefordfleet.com and download the official Ford order guide for the 2003 F-350 Super Duty Pickup. All the ifs, ands, and buts of ordering are included. Pay attention to detail, and be sure you're looking at the DRW pages before you fall on your sword about something.
