In answer to your airbag question, a minimum of 20 lbs pressure should be kept in the bags, and a maximum of 100 lbs is the most.
Most of us, myself run 60-80 lbs, depending on the weight your carrying.
I have found that for my 283ts if I keep it at around 75 lbs, it gives me the best, smoothest ride, along with my tire pressure which I also keep at around 75 lbs.
Your going to have to experment a bit to find what is best for your rig.
