Time to tow with our 2006 GMC Yukon XL Denali!

I will also add that my '01 Suburban is wearing rear axle #4, and I had several failures while on vacation due to overloading. My Burb had the self-leveling shocks, so it wouldn't sag no matter how much tongue weight I had. You'll have the same issue with the AutoRide - it will level the truck regardless of your tongue weight/WD setup.

Make sure you check your weight on scales, keep an eye on your rear axle weight, and don't exceed the rating.
