Car Seems to Sag When Parked on Hill. Is this a problem? (pics attached)

I recently noticed that the car sags when parked on an incline, ie some tires seem to be closer to the frame than others. I recently hit a pretty big bump at 30mph, and I'm wondering if I have a problem that needs to be fixed. I've only owned the car for a short while and just recently started parking on this hill, so I'm not sure.

If it only does it on an incline, then it's probaly just the car leveling itself. The car automatically adjusts itself for heavier loads. If 2 or 3 heavy people climb in the rear of your car, the car will raise the rear to compensate, and level the car. This is why you must turn off the air ride when jacking up the car, it will try to adjust itself for the change in sensor height. The incline may be changing the normal sensor position.

It MIGHT be a leak in an airbag, that only leaks when the incline positions the airbag slightly differently from it's normal at rest level position (exposing a leak that's normally sealed). You can try turning off the air ride, while it's level, then drive up on the incline. If it still sags, when you check back later, then it's likely a leak.
If it sags, leave it a little longer and see if it sags even more. If it doesn't, it may be sealing itself once it reaches a certain height. If it sags, but eventually stops, you can probaly live with it for a while, but you better start saving some money for new bags in the foreseeable future. If it continues to sag, then new bags are soon to be needed (sooner than later). If it doesn't sag, then it's probaly just the air ride adjusting itself. Turn the air ride back on.

If you want to get rid of your bags let me know, I'm trying to get rid of my Coil Spring conversion so I can have the air ride again.

How does parking on an incline affect ride height? The height sensors simply level the suspension to the car frame/body. There is no reference to the ground. ::wtf::

Bear in mind that the passenger rear doesn't have a sensor and can move up or down without affecting the sensor height. If the rear passenger side is on the incline, it will appear that the rear end is sagging on that corner (and the airbag will be compressed from normal).
