From Council Bluffs IA and have a '05 XL Denali with around 160K. Mostly kid hauler and grocery getter. Was towing a travel trailer with it but have a truck now to do that duty since the size of the trailer was getting pretty close to the limits of what the Denali liked to pull. Didn't care for the 6-8 MPG towing either! lol Auto ride was shot so converted to regular shocks with Air Lift 1000 bags which other than the back sitting a little higher than I would like (I'll probably get used to it) is working out great. Still have the SERVICE RIDE CONTROL message but will tackle that soon with some resistors. Only other issue is the TPMS monitor... will need new tires soon so I'll tackle that issue then. Glad I found the site for research to fix the issues I have had and the ones to come.
