well i'm looking t getting into a used 2500. hopefully a diesel. maybe something in the 2006 range. i want to get something with lower miles, anything i should look out for? i have always heard about tranny's and dodge, will i be looking to rebuild it after a cedrtain amount of miles? i plan on lifting it 4" with 35's for the summer and 33's on the stock wheels for the winter where i tow my sled trailer. its going to be a second car/truck. i know the motors will last for ever but what about the rest of the truck? can i get 5 good years out of it?
