I hate the truck so much that I put a non-op on it and parked it.Just another 2 cents


Wow, first time I've heard that (less power than a gasser). \:o

Which year Cummins did you have?

Was it out of a Dodge or other on road application?

I'm not trying to criticize, I'm just curious what went wrong.

Edit....

By any chance did it smoke excessively?
