It was a company truck for an equipment rental company in Montana.
Maybe someone liked to take the company truck wheeling? Check the frame piece that rad mounts onto for cracking. Check were it mounts to the frame as well. The springs and suspension may have been tweaked too.
Looks like an F-350 from the front wheels. What kind of diffy does have in the front?

I'm guessing that the Centurion conversion uses Arrowcraft products to achieve the dually status on the F250 chassis. They did a good job filling the viods that ford left behind as far as cab and drive line configuration goes. Ford never made an extended cab dually 4x4 in our vintage so Centurion built this truck just as it built the Suburban beaters. Funny how Ford caught on by the time the superduties came out in '99.
