Best Shocks for Towing

[aklim]

I have an 02 GMC Yukon XL that I will be using for towing about 8000# of trailer in a Toy Hauler that is hitched behind. For the most part, the SUV will be used for towing and not street use except maybe once in a while. As such, I am not concerned if it rides rough. What recommendations for shocks does anyone have? Should I pony up for the adjustable ones or just some stiff ones. I know I will be getting "C" rated tires so that will help some. TIA

I would recomend adding air bags to compensate for the weight. Shocks cannot help you there.
