I've found one that has around 103,000 miles on it with a nice bale bed. It runs good but has a head gasket leak. Waiting for an estimate from my mechanic for cost to fix it. I haven't talked to him yet about his impression of this engine. Diesels is all he works on. Would appreciate any input anyone has who has had experience with this engine. It is a 3500 and overall a nice truck. Is the head gasket a normal issue? Anything else I need to check for?
