Question from a dummy

I have a 2011 Pleasure Way Excel TS it is a Ford E-350 Super Duty wide body. It has Firestone air bags on the rear that I usually run at 60 psi. So when hit with side winds, do I increase or decrease the air pressure?
Thanks for any help.

Increase, to firm up the ride and reduce sway, would be my opinion.
All comments are my opinions, and worth exactly what you paid for them.

Increase the pressure to reduce the sway, but ride quality will suffer. Increase the sway bar size (if possible) or add a sway bar if needed to reduce the sway and retain some ride quality.

Adding air to the air bags stops the leward side spring from compressing but not the windward side from stretching.
So they help a little while making the ride harsher.

If you install heavy duty, anti sway ( roll ) bars, it fights the sway from side to side with little added spring stiffness.

I should add that I have a Roadmaster steering stabilizer and a traction bar on the rear.

Steering stabilizer helps you point the RV straight ahead.

Track bar helps keep it from moving like a weather vane.

The wind is pushing the whole side, front and back, making it lean like a tree in the wind. Anti sway bars fight against that.

Increasing air pressure in the rear will also raise your coach up several inches. Might actually have more sway.

I run my airbags around 20 lbs in 24' Class C. Raise and lower pressure mostly to get into steeper driveways and campsites.

Love the smoother and less vibration ride with the rear airbags.

I'd just leave them alone as it will make little difference.
