Its been a few years, but our old truck, 3/4 ton GM with the 8.1 and Alison. Traded that in 2015 for a Chev Duramax. My first Diesel. I won't go back to gas. So much nicer when towing. Actually, nicer all the time. No issues with maintenance. Haven't had anything maintenance wise that would be different between a Diesel and Gas. The dealer I bought it from does free oil changes for life, so no cost there. I have to buy DEF, but that's pennies, maybe 5 gallons per 5K miles.
I thought the 8.1 was great, until I got a Diesel. I really appreciate the power, torque, and gas mileage. This was purchased as a daily driver for my wife and she loves driving it.
There must be a huge difference in the Duramax from 2004 to 2015.
When I bought my 2002 8.1L, I drove a low-mileage 2004 Duramax the night before. I was not impressed. I mashed that pedal all the way to the floor and ho-hum.
That 8.1L put your butt back in the seat, and still does all these years later. It even outperforms Dad's 2015 2500HD 6.0L. On paper it should be able to run with the 8.1L, but it just doesn't have it.
