Has the ride slowly gotten worse or did it happen instantly? Unless the suspension is binding or frozen (unlikely at 22k) you have shocks, air bags and tire pressure. With the rear ride height sensor keeping the height consistent, the more weight in the rear the more air pressure in the bags.
My Seneca rides noticeably stiffer with a car trailer hooked to it due to the extra pressure in the bags to keep the ride height the same. Your sensor could be out of calibration doing the same thing with no trailer.
Your rear shocks could be bad already. Just had a truck with 46k miles in my shop with a siezed shock. It would jar your teeth out.
You have too much air in the tires for your load. I would take Grumpy's advice. Tire pressure is the easiest thing to adjust for ride.
Don't we have a 5yr 100k mile warranty on our chassis excluding wear items like brakes, tires?
