Our teeth are rattling out of our heads...

This sounds like a drive train issue. I would look toward the front CV axles especially since you mention it changes with steering input.

Agree with this... If the issue gets worse by going faster, it's an imbalance somewhere. The turning is largely due to transferring the "force" onto other parts of the vehicle, so it's still happening, but you won't notice it as much.
Anything that rotates should be checked, tires, rotors, CV axles, bearings. (if you feel it mostly in steering wheel vs the back of your seat, it's more than likely front).

The damn thing is choppy. HD tow pkg, 22s. It chops and crunches over everything. The sunroof thumps and clicks, the seats spring board constantly. The roads aren’t bad but they aren’t great. This thing rides very firm. My 25 Silverado, 2012 Tahoe, and 2002 Excursion were/are all way better.

I understand the rubber band tires on 22s and I did throw on Michelins 6 months ago. 10% improvement. It’s a very firm ride. Most of the time it doesn’t bother us…it’s the interior noise. Everything in the vehicle gets thrashed while riding over an old weather worn street.

However, I love the handling. It stays flat on the road and eats hills and curves. 8 people, tandem axel boat on the hitch, tons of junk in the cargo and it’s smooth and quiet.

We’ve managed to tackle a few of the thumps, chirps, rattles and ticks. Cleaned and lubed that stupid pano sunroof and tighten the oh shit handles, a little attention towards how we secure our items.

If you understand the rubber band tires on 22s (Ghetto Bling "Rims") why are you still using them? You know the solution so why are you not fixing it?

I admit the 22s look good at the yacht club but I refuse to put anything bigger than 18" on my Expedition (truck) which solely exists to tow campers and boats and has a "Town Car" ride the rest of the time.

My Platinum rides smooth as glass on my Michelin Defender 285/45 R22 tires. I don't know what to tell you, unless you have worn shocks, bad bushings, etc.

Might be a "frozen" shock.
