Mine is an 03 Quad Cab 3500 Daully. Just turned over 254,000 the other day. New trans at about 175K front end has been done...several sets of tires.
Injectors on mine are crap...still stock and have had 2 replaced and it still won't start without being plugged in below 60 degrees. Lift pump has been replaced once. I need to look at what the aftermarket has available to replace the lift pump and filter housing as I think the lift pump is going bad again.
Doesn't matter what it is but every trip to the dealer is North of 800.00. F-em It'll never go back...
Still love the truck just hate the crooks at the dealership...
