Curt rates that tube at 5,000 lbs.tow capacity and a tongue weight capacity of 500 lbs.
Hope this helps.

billtex,

That link does NOT calculate or show how much the receiver is derated. It simply tells me how much weight is where on the truck.

Where do you get your information on how much the tube is rated for?
