Wanted to say hello and let everyone know how helpful this site is. I am new to a diesel. I traded up from a 2002 2500HD with the 8.1. Wow, what a diffence in towing (and mileage). The 8.1 did fairly well with power/towing but nothing like this diesel. I have pulled the camp trailer on a couple of short trips and it is amazing how well it does without all the downshifting to go up hills. I am really getting the bug to get out since it has been 60 degrees for 3 days in a row now. Thanks again for all of the help with things like the fuel filter changes and what oil to use and so forth.
