My first Chevy Duramax worked great until I took it in for a manufacturer recall regarding reprogramming something in the computer. After the dealer had it, my "check engine" light would go off and she'd go into limp mode. First time was in NYC pulling a car trailer. Try maneuvering around Harlem in limp mode to get back to the nearest dealer in NJ. They said it was fixed (some sensor thing). Several months later the same thing happened (this time closer to home). My local dealer had it for a week. They said it was fixed, but I never trusted the truck after that. I got rid of it. Could not take the chance of having the thing break down with the TC on thousands of miles from home. My next Chevy Duramax has been great.
Reliability is the most important issue with any vehicle. If you can swing it Id dump the thing. I wouldnt turn my back on Ford, but Id look at all of them and buy what I like the most.
