When do you think its time to sell or trade in a truck or equipment I.E. trailers, mowers, etc? Right now my 94 Dodge is about to turn over 200K on the 5.9L gasser. It doesn't leak from the head gaskets, and doesn't consume any fuilds. I've replaced a water pump, thremostat, altenator, battery, a lot of the sensors, exhaust, and had the trany rebuilt about 20K ago. The body is showing some age, its a WI truck so the salt has started to rust out the cab corners and rockers. Personally I bought it for 900 bucks in 04, being that it is 2wd does hurt so I'm looking at getting something 4x4 and newer/heavier. I'll probably only get 500 bucks on a trade for it so I thought of just keeping it and running it into the ground, well replacing things that need to be replaced. Also anybody know why a check engine light would come on after replacing the PCV valve?
