I recently purchased a 2003 Expedition with the 300 HP Cummins. It had 20,600 miles and the last 9 years, the previous owner only put 4,000 miles on it.
In the weeks before I bought it, the previous owner replaced one A/C unit, the Inverter/Charger, and the batteries.
My first trip out, I had fuel delivery problems due to an inline fuel strainer that the previous owner did not know existed. Freightliner also did not know if the fuel strainer existed. It is an installed item by Cummins.
I "polished" the fuel by running it through an external pump and filter for 6 hours after adding a fuel additive and a biocide.
I changed the air cleaner filter and the two fuel filters myself and completed a 1,100 mile trip with no problems.
I also had a local truck service facility (owned by a personal family friend) service all fluids, lubricate, replace air drier, replace serpentine belt, and check all systems. The plastic radiator surge tank had spider web type cracks in it and was also replaced.
New tires and batteries is a plus if they are quality items.
Make sure all systems function and have recent required service - such as the generator, filters, serpentine belt, etc.
Maintenance items are not cheap.
