I am not bashing GM here, just reporting what I have seen. I have been going to northern New Mexico every summer for the past 5 years. Every year I see the same thing. Duramax trucks towing 5th wheels on the side of the road with the hood open boiling the coolant out, usually at the top of a grade. I do not see this with the Cummins or PSD's.
