Amped 28FS Sway Issues when towing....need help!

I would give the 20psi in the bags a try. You should be using the weight dist hitch to regain ride height on rear of truck, not the air bags. And 80 psi rear tires:)

Air bags should be used to help control the bounce (up and down) while traveling down the road. Start at 20 psi and add 5 psi until you get a ride that feels good.
