Road Bounce

I have a F350 for towing a fifth wheel trailer. My truck is fitted with airbags for the load. When I am driving with nothing behind me I get the most annoying bounce. It almost makes you want to stop its so bad. What can I do to this truck to eliminate this? Your help will be appreciated.

I usually carry @50 psi. Sometimes it's on concrete road. Once around Oxnard California I almost had to pull over it was so bad.

I use air bags on my F350. 30-35#s while towing (2650#ppin weight), 5#s when not towing. Tires at 80 psi while towing, 50 psi when not.

Air bags at 50 psi with no load, takes most of the flex out of the rear suspension. Very rough ride.

Well, there is your problem. You have to let them down when running empty. Drop to 10psi or less and I guarantee you that you will see a huge difference. 50psi is pretty much eliminating your shock and springs when empty.

When empty I run mine at 5 psi and dont feel any difference at all compared to when I didnt have the air bags installed. I run 30-40 psi when loaded and if I forget to air them down after I unload I can feel the difference on the very first bump I hit. You didnt mention if it was a dually or not but my experience with past dually's was that they rode better with a load, even with no air bags at all.
