2005 Envoy air bags leaning

Yea, another gripe about airbags.
I replaced air bags, both sensors and bump stops thinking this would solve problem of my '05 Envoy from leaning. The bags were leaking but still leaning after newbies. I have adjusted the sensors by the manual. Even tried adjusting the sensors with both rear wheels off on level ground measuring from ground to between quarter panel and rear door intersect with yard stick. Still leaning about 1" to 1.5". I then installed quick connect tees in both air lines and ran to separate schrader valves. I pumped each side to 50 psi and let truck sit for 5 days. Both still had 50 psi and truck was level. Ran around town and checked. Truck leaning again with 50 psi in left and 30 psi in right. Let truck sit 3 days and checked again. Still 50 and 30 psi. So now with schrader valves, I attempted adjusting again with wheels removed. I can now get the body exactly level by adjusting the air and reset the sensors. Nope still leans the same. My next attempt will be to tee both air lines together so both airbags will have same pressure. I don't know if compressor can independently adjust each side but seems to be the right side is 20 psi lower than right. When I hang my camper on the rear, she does like she is supposed to and raises the rear. I have no codes or alerts on the display.
Sorry for the length but this is the short version. Comments? Thanks.
