I currently tow about 5k pounds with my 08/5.6L. I've towed with and without the WDH/Sway control. All I can say is spend the money and do it right, regardless of the weight. Specifically, I use the original "equal i zer" brand and it tows absolutely straight and the back end stays relatively level. I just bought the airbags and will add those just to stiffen things up a bit.
Just my 2 cents....
