I believe wholeheartedly that the truck that you have your mind set on is the best truck out there in your price range.
I bought into the whole "cheaper" rhetoric years ago and sold my 03 5.9 manual and bought what I thought would be a much cheaper truck to drive, an 02 new body style gasser with a manual as well. I hated that truck more than any truck I've ever had, It rode horrible, drove poorly, and didn't have enough power to drive freeway speeds (it was a 4.8, or 4.6 or whatever the small V8 was) and as such I usually only saw 11-12 mpg.
Just as soon as I could I sold it and bought an 04.5 5.9 manual. My current truck is my baby, finally got it paid off and am able to put some money into it. Just did a KORE 3" Recon system with the FOX 2.0 remote res shocks, and all the other Carli goodies and it is now by far the best riding ad driving truck I've ever had. As well as being one of the more off-road capable (for its size) vehicles I've had.
Drive-train is SOLID, that being said, with a Dodge its no secret that the rest of the truck will nickle and dime you a bit, but as long as you keep up on the body, and the constant little broken interior parts and switches and what not, they are still my favorite trucks. I do feel that Ford probably has the best body followed by Chevy.
