The 95 2500 company truck I had puffed when it started and when I pulled our 15K lb trailer, it would certainly leave a trail of smoke from the day we got it. I was one happy camper when GM dumped that engine and came out with the Duramax/Allison comination. I knew a couple of people who had the 6.5 in 1/2 ton trucks and loved them because they got good mileage with them.
