Sure I got somethings good to say.... I've owned a 05 Super Duty and traded it in with a little over 170k miles. Other than some oring seals to fix a oil leak, and upgraded to the inductive heat flash that was one excellent truck.
I just completed a trip to Florida and saw more Super Duty 6.0 PSD trucks one way than I saw Cummins powered trucks both ways. There are a lot of these trucks still on the road.
Stick with Motorcraft or Racor oil filters and fuel filters "Only" you'll be good to go. In addition having the latest flash (cost about $100) will monitor ECT and EOT delta and warn you if the delta exceeds 15F which could mean your oil cooler in plugged. A coolant filter from Sinister is also a cheap and worthy upgrade although I never had one on my truck.
How many miles on your truck?
