I drive a 05 dodge ram. I had to have the water pump replaced about 5 months ago. It cost me around $200 replace, including labor. I also have a 1999 1 ton dodge with v10. Next time it breaks down, i'm going to have it smashed! The 03 plain jane 3/4 ton dodge with Cummings and standard transmission hasn't cost me a dime, other than when one of my dummies put gasoline in it ($3,600 fix).
The 03 1 ton ford diesel has done ok. It's had some strange things break on it, but they didn't cost much, and it's fun to drive.
Also have a 1994, big ugly brown 4 door 1 ton Chevy with one of the weak gasoline converted to diesel engines. It won't die. It knocks, smokes and everything else. It hasn't really seen the highway it's whole life. It was a farmers hay truck, then I put it in a oil refinery about 6 years ago.
My last personal truck was a 3/4 ton 4x4 chevy. It was a money pit.
