Is it possible that you are overinflated and are running on the center of the tires?

As others have said the very first thing is to get front and rear weights, then check tire mfg website to get proper psi based on weight. In the meantime, go ahead and check tire mfg website and see what weight corresponds to your current 125 psi.
I checked Michelin and as example, a tire sized 235/80/22.5, max inflation is 110. At that psi the front should weigh 9,350 lbs and the rear 17,640. Here’s the link.

Hello, Back with a little more information. My class A has leaf springs. I am also looking into the idea of adding air bags to add to stability. Is this a good idea?

I would definitely start with new shocks and bushings on a rig that old. Then a four corner weight and load and tire pressure adjustments. Next an alignment. See what that does and we'll advise from there.

You have 125 psi in your tires, this is too much, been addressed earlier.

Get the tire chart for your brand of tires, without weighing it you can lower the pressures to the max carrying weight of the tires.

Fix your tire pressures and then go for a drive.

I have a W22 and I am almost at max weight, my run my tire pressure at 95psi

Been there done that. I have added the following to my W-22 (34 foot long with 208" wheelbase):

Front and rear trac bars
Front Sumo springs
Rear anti-sway bar

Trac bars fixed most of the tail-wagging-the-dog effect during cross winds or from passing trucks. I'd do this first.

The front Sumo Springs are not terribly expensive and helped with the roll and made the coach feel more buttoned down. Also softened the ride a bit, though big bridge transitions will still bottom out the suspension at times. They're a no-brainer considering they don't cost a lot.

Rear anti-sway bar also helped a little more with the roll, but because it's expensive I'd leave it for last and only add it then if you need it.

The combination of all the above have made my coach a lot more comfortable to drive.

I had air bags on a previous P30 class A. They helped with the roll a bit but passing trucks still pushed it around. Not worth it imho.

Cheap handling fix (CHF) mentioned in previous posts is not applicable to Workhorse chassis.
