Hey y'all I have been a member on dtr for a while...but own a 1st gen...so haven't posted over here yet. Here's the question...i found a 1995 3500 4x4 reg cab in mint condition.....but the motor has an odd white "X" on it and the p pump has the injectors marked off with red dots. This may be an absurd question..but I have never seen this...is this common? What does it mean? (owner did not know....and he is the original owner). How much is this truck worth? (truck is absolutely mint, owner is 55+ years old, has towed nothing more than a john deere garden tractor, southern truck, leather, two bedliners, tires are 70%, running boards, seat covers, arm rest covers, 86,000 on the od). Thanks for the help. redwake.
