The tires can cause a rough ride, are they aftermarket and is the truck lifted? Also, the tire air pressure can make the truck ride rough. Is there any noise when the truck is traveling over bumps?
Here ar the front and rear suspension diagrams (below) to help you see which component might be causing the issue. Really the only thing other than the tires is the shocks. Can upload a video of the problem so I can see what's going on, that would help.
