Greetings, all. Purchased my truck a little over 3 months ago. It has the Denali Ultimate package in Satin Steel. I love it! Recently had a 700 mile round-trip and averaged 30 mpg, mostly interstate driving at 70-75 mph. Only upgrades so far have been GM all-weather floor mats and a bed cover. I just discovered this forum and look forward to reading some of the posts from others.
