Class A suspension

We Bought this 36 foot bounder with a tag axel 3 years ago
It rocked like a John boat in open waters of the gulf of Mexico.
First problem I found all the sway bar bushings where gone as in not any left.

It drove better but still white knuckle driving

Just this past month we replaced all 8 tires old ones where only 4 years old but they'll do just fine on my 3500 4x4 4 door dually
(Not going to wast tires)

Changed all 6 shocks

Found out we have a safe T
Sterring stabilize so we left it on.

So this made a big difference not white knuckle driving but still better pay attention to 18 wheelers sneking up on you.

All n all I think it drives 75% better then before.

Does you Coach have springs or air bags?

One of the biggest handling improvements I made to my Coach was getting it weighed and putting as much weight on the front axle as I could (within Axle and Tire ratings). The more weight on the front the better it handles. I am able to adjust the weight distribution from rear to front by adding air to the tag axle air bags (and moving the heavy stuff in my cargo bays to the front bays).

Also, too much air pressure in the front tires will also contribute to wander.

From your pics it appears that your hitch ball may be a bit high. If so it may be transferring more weight to the rear of the coach and thereby making the front a bit light. Does the coach handle much different without anything in tow?

That's a gas chassis coach with spring suspension, with a tag added to goose it up for a heavier body than the chassis is designed for. Not too surprising it doesn't handle well, especially with that heavy car-hauler trailer out back. That's got to exceed the tow rating for that coach, which I'm betting is 4000 lbs. I owned a similar 36 ft Fleetwood Southwind tag of about the same year, so feel qualified to speak on that point.

In my opinion the most helpful chassis upgrade would be a track bar (panhard rod), probably on the front axle for that set-up. Maybe air bag assist in the back too, to help stabilize the back end.
