The specs on a light crew cab 1500 (LT) show:
weight 5333
payload 1740
The door sticker will surely be higher weight and lower payload.
I've had a Silverado. Avalanche and Tahoe with the 5.3 and now the 3.42 rear end. I love the engine for it's reliability but it's a weak engine for towing. I have towed a 4,000 pound (real empty weight) and the same trailer weighing 6000 pounds. The 4000 weight I've towed long distances and the truck did pretty well. When weighing 6000 pounds I towed it locally and would not want to tow it a long distance or up mountains. I think the truck would do it, but I would be a nervous wreck.
