I've weighed disconnected before. Ask first. We needed to weigh the force on the front feet of a 5th wheel.

If you weigh with and without the distribution bars stressed you will get the tongue weight also of course weigh truck without trailer.

I would get the tongue weight down you are over rated weight I think about 6000 gross is limit but not sure if you are allowed to go higher by adding tongue on top since it's low Cg. I've weighed in at 6600 myself but my run on flat tires are rated 500# each more than my previous tires.
