I bought mine used 3 years ago with 70k, now she has 90k. I've had to replace the power steering pump and rear bumper -- rust is an issue with these trucks. Other than that, she starts up and runs like a charm. I have a 7.5' Western plow and she plows like a champ.

Rust is an issue. I don't have any on my doors, but it seems most RAM's rust out at the bottom of the doors. My bumper rusted out from the inside and looked like Swiss cheese in a matter of weeks.
