I have a 08 GMC Yukon Denali with 6.2L eng and 3.73 gear mated with a HD tow pkg and wdh. I ran from Texas to SC and hardly knew it was there. Used the tow mode all the way. Yes, mpg was 9-11at best.

Pulling a Crossroads Slingshot with a dry weight of 3650' but am probably loaded up to about 5000lbs.
