OWNER SAYS:“ In the past, I have owned a 1996 3500HD dualie and an 2003 2500HD -- both with gas engines. My 2012 first diesel, and I love it. I bought the truck new in April 2012. No heavy mods yet -- I am waiting until the warranty is up. When the day comes, I would like to tune it and add a water-methanol system. I tow a 37-foot fifth-wheel trailer with no problem."
