3406B model cat engine
The oldest truck that I have driven is a 2006. It had a C-15. I'm in the market for one with the apartment size sleeper on it as we are a cross country team.
I found a truck that fits our needs and appears to be in good shape. My next step would be to take it to a shop for a good going over except for one major question.
It has a 3406B in it. Since I have only driven and dealt with electronic controlled engines this one has my caution guard up. Before I spend money on an in depth evaluation of the truck I would like to know exactly I'm getting into. I've heard good and I've heard bad, and I'm not afraid to ask of those who have been around longer than I have.
Is this a good question?
