It's easy to get confused with terms such as GVWR, GCWR, GAWR, etc. Here is an easy-to-follow guide that describes these weights.
https://www.curtmfg.com/towing-capacityDo remember these are static weights and do not necessarily describe what happens when the rig is out on the interstate with a stiff side wind and a semi blows by at 85 mph. Just hope it's not downhill and you have to suddenly brake or swerve to avoid something in the road. That's where weight distribution and sway control come into play.

We're probably due for another check, since there is a tendency for more stuff to be added over time.
