One local here in NH bought an 2008 f350 power stroke. He hates it! He is very talented mechanically and has alot of heavy equipment etc. His truck gives him much worse mileage than his 1999. He really wishes he had waited. I know this doesn't help you but you are not alone.
Want me to contact Ford for you? I was fairly successful with Kioti with the help of alot of Kioti dealers acting on my behalf.
