Bob,
You did not say what year and model Patriot that you have, so I will assume that it is a 8 air bag coach. The ride (travel) height is controlled by 3 sensors. One sensor for each side in the rear that controls the rear height and side to side height difference. You also have a sensor in the center of the rear of the front suspension cradle that controls the front suspension ride height, but it has no control on side to side tilt since it is mounted in the center of the coach, and it can not detect a side to side height difference.
So if your coach is not level from side to side you need the rear sensors adjusted. It is a simple repair, but you need to set the ride height at the proper level for proper drive shaft alignment, and it can be dangerous if you make a mistake and lower the coach onto yourself. So if you are not experienced in suspension work, you might want to have a professional do it the next time that you have a trusted mechanic (not just an oil changer) service your coach.
