My bad! I didn't read close enough. Autoride is not available on the 3/4 ton.
Does your Denali have load levelers? I thought they came stock on the Denali's. I have been wrong before.
SD,
The Denali does come stock with rear air-assisted load leveling and full-time all-wheel drive. I just figures the longer wheel bast and the weight of the trailer would cause some sag that the load levelers could not compensate for. Never towed with the truck before it is new.
Maybe the Denali package makes it look lower than it realy is...
