I tow a 28 foot camper behind my '09 1500 (5.3L, 4 speed auto). The camper lists at 8k lbs. I have a weight distributing hitch, and a brake controller, and a sway brake. It still moves around in the wind, but you learn to compensate, especially when big trucks pass. The trans temps reached about 215 on a recent trip, with ambient air temps in the 90 degree range, and engine coolant running over 210, but not 220. That's up and down some major hills, and with a significant load in both the camper and the truck. I'm going to add a better trans cooler. That's a little too hot, for me.
The worst of it is, my towing MPG runs about 8! The new tires (Goodyear Wrangler MT/R (with Kevlar)) actually cost me about 1 mpg over the factory ATs! Ouch!Kevin Singleton '09 Z71 - PA ZRT - kevindsingleton.com

If the 8,000lbs is including Supply's.....meaning Food and Gear etc........the Tow Ratings for a.....2009" Ext or Cew Cab 4WD 1/2 Ton with the 5.3 liter W/4L60e and either 3.73 or 4.10 Gears has the Following Tow Ratings,
.....With 3.73 Gears......Max Tow Rating Weight is......7,500lbs and the GCWR is....13,000lbs
.....With 4.10 Gears......Max Tow Rating Weight is......8,500lbs and the GCWR is....14,000 lbs
.....if you have 3.73's.....your over limits of what your Truck can Safely Tow and if you have the 4.10's you are Close to the Limit's of what your Truck can Safely Tow .
