I've owned three different size truck campers and have used 5 different trucks up to one ton DRW under them and they all had a bit of body roll. You shouldn't expect a stock ride. Some folks pay no attention to a bit of rocking and rolling and others can't tolerate it.
I would also deflate the air bags if you haven't already and see if there is a difference.
The camper to cab shocks dampen camper up and down movement. Years age we bolted truck campers through the floor and into beds frame work or turn buckles in the beds stake pockets which made Camper Damper shocks necessary. A TC mounted this way has lots of up and down shake at speed or especially strong head winds/semi truck wind blast/etc.
