I'm only 30lbs over RAWR

This is with an empty trailer.
I'm hoping it will get under specs when I load the garage (behind rear axle).
We'll see Sunday when I weigh fully loaded
Jerking, bounce, (chucking), can be caused from too light of pin. I don't think this is your issue, as a TH usually has a heavy pin with an empty garage. That said, making the pin lighter, loading the garage may increase your chucking.
If the rear suspension is sagging from the load, you may want to add Timbrens, or airbags to level your load, and add stability, which may help your chucking too.
It is normal to have a little jerking, especially on concrete roads. Most of us can remember a certain section of roadway, that has caused some pretty noticeable chucking. A high end air hitch, may help, but expensive.
Your weights aren't great, but not a disaster either. Your truck is designed to operate at max RAWR, and your well under your tire max. Many are towing a little over GVWR.
Good luck, hope you enjoy your new to you TH!
