Since it is a work truck it could be well worn, even at that low of mileage.This is things I would look for:
Check for wetness on the backing plates of the rear brakes which would indicate the the rear wheel hub seal is leaking. That is an automatic brake job.
Check both drive shafts. Grab the front drive shaft and see if you can move it up and down. If so, is it the u-joints or worse, the spline slip yoke, that will require the drive shaft to be rebuilt, ie cut and welding a new slip yoke, and rebalanced. Repeat for the rear shaft assembly.
Check the springs, are the mounting bolts in the center of the spings bushings or have the bushings collapsed and the bolts off center now. Also are the front rubber spring stops show that they have been hitting a lot? Are they too clean from constant use or even broken? If so the front springs may need to be rearched and/or a spring added.
Check the front axle carefully, look at the axle u-joints, leaks from the axle shaft seals, steering linkage, rotors and calipers. If you are lucky enough to pull the right front wheel, check the brake pads for even wear at both ends of the pads. Since these have double piston calipers, rust will cause the lower piston to bind sooner that the upper. The result will be brake drag and uneven wear.
You would have to ask the psd guys for sure, but this is what I remember on the PSD. The valve cover gaskets are quite expensive, so check for signs of a damaged or leaking valve cover gasket. Also look for over heated glow plug harness since the harness can be shorted and require removal of the valve covers. Make sure it is running on all 8 cylinders evenly, their injectors run $200 each.
