2006 F350 XL Crew Cab Dually Diesel

I bought this truck with a trailer for my son to get into the hotshot business. He lasted 5 months. I would like to get some of my money back. Already sold the trailer. Auction starts at 50% of Kelly Blue Book price.
2006 F350 XL Crew Cab, ' x 9' all-steel flatbed, ual Rear Wheels, Diesel, 90,000 miles. This truck had an honorable worklife for a service company working in the local refineries before I bought it at auction. It was greasy dirty, ut mechanically, t had been well maintained. We scrubbed the heck out of it, nd then updated it with the following new parts to make it a reliable over-the-road truck:
All new fuel injectors
New batteries (two)
New starter
New power steering pump
New front rotors, earings and brake pads
New fuel pump
New fuel regulator
New EGR valve (since deleted)
New radiator
This truck runs beautifully, ven pulling 12,000 lbs. up a mountain. If you know anything about diesel engines, have a ScanGuage and can provide all the data you need to confirm that it is running perfectly. I have no doubt that this truck will give the new owner at least 100,000 more miles without major repairs.
It is a work truck, nd does have its share of nicks and scratches, nd two small dents - one of the driver's side front fender and another on the rear bottom corner of the cab on that same side. It also has the obligatory torn driver's seat (is there a used Ford truck without a torn driver's seat?). Otherwise, the rest of the interior is very clean and serviceable for a work truck - this is an XL model with bench seats, manual windows/door locks, tc. Couple of tires are almost new, he other four are about 50%.
