thanks man but its against my religion to buy a new vehicle off the lot. one of the major things ruling the fords out for me right now is that they seem to be more reliable than the 6.0 or 6.4 but still the least reliable of the group. Plus if/when something does break I dont think I can work on it as easy as I could the cummins.Another one of the opinionated things. I'm a powerstroke guy myself, like the duramax too. Never been a dodge fan, and can't stomach the sound of a cummins. I really don't think you could truly go wrong with any, whichever you like the most, I'd go with it. Even if it costs more, if you settle because you wanted to save money, you'll never be happy, or at least you'll always wonder.
If you are thinking new, I worked at Reynolds on NW Xpressway for a while, I can get you straight to the GSM so you don't have to deal with salesman. He's a great guy, and just wants to move trucks.
Good luck either way!
