Keep that truck! Just maintain it and upgrade certain things like belts,hoses,coolant as others have advised. Hey,call me crazy but I bought my sons old 1993 Dodge diesel with 280,000 on the clock and we are taking that on trips. Getting a retro trailer to go with the old truck which will match the old f**t driving it. I went through the truck and replaced all belts,hoses,thermostat,radiator. All new brakes including master cyl. Shocks too. Tranny was redone at 240,000. The engine just runs great. No worries. Enjoy yourself!!
