if youve owned a ford I doubt youll be happy with a dodge, fords are the best truck built, the diesels havent been the greatest but I was in the same deal and bought a dodge and hatted it every second I owned it, theres only one good thing about a dodge and even its overrated. like stated above there cabs are little, even the ugly megacab, there cheap built trucks, they dont weigh much so the wind blows them around. every one I know has put balljoints on there dodge at 40k, and if you look to buy one everyone is so proud of them you can buy a new one almost the same as a used one, on the other hand so many people are so scared of the 6.0s especally the 03-04 that you can buy a nice truck for a sweet deal, I had a stock late build 04 that ran great, I loved driveing it, the tranny in those trucks rock, you dont even really know when its shifting its so smooth, do however research before buying a 6.0. a oasis request, is it under warranty, check it out or take it to a shop to check for egr-headgasket problems.
Ive also been hearing awesome things about the 6.4... 500hp on a tuner!
and if that dosent work buy a ford and drop a cummins in it, trust me you will regret buying a dodge.
