2001 Dodge CTD completely stock had 70k on it when I purchased in 2006. It now has 147k on it. Keep the fuel tank at least half full to avoid lift pump trouble, every other tank of fuel a little cetane boost, every 5k oil change, every 10k fuel filter change, every 35k auto transmission service (all suggested to me by my local mechanic). Repairs to date; serpentine belt, thermostat, replaced original batteries, rear differential leak. At least half of my mileage has been towing my 21' bass boat. MPG highway 20, around where I live 18, towing boat 14, hauling the NL T/C in and around the Sierra 14.5. I could use a long bed 3500 dually now but then that would require a new 10' NL and I would have to get rid of the current truck....would love the T/C but getting rid of this truck just ain't gonna happen!
