This is my first deisel and I love it! This thing tows my toy hauler trailer like it's not even there. I have had no issues at all and I have 4K miles on it. I get 12- 13mpg towing and 15-16mpg not. My brother has the Dodge and I feel that the motor in the Chevy feels much more refined.
4X4 light on dash when engaged. It's easy to forget that it's in 4 wheel drive.
