Pin weight is somewhere around to 20% of the trailers gvwr. So if the trailer's gvwr is, say 11000 lbs pin weight will be about 2200 lbs.
And yes the advertised pin weight is trailer empty as it leaves the factory.
Remember everything in the truck including you and wife, etc is counted as payload. So if pin weight is 2200 lbs with two people, hitch and cargo your looking at 2800 lbs to 3000 lbs total payload.
And one rule of thumb...You can't have too much truck! It's always better to have too much than just enough.
Good luck shopping.
