I pull a small popup camper with my Bonneville and the rear end sags quite a bit. I have air suspension in the back and I can hear the motor run a lot with the camper attached. Everything seems normal without the camper attached. I'm not sure if it's something faulty in the suspension or if I just need extra support. Does anybody know if I can install an AirLift system in addition to my current suspension?

It's been a while, but I think someone put helper bags in their rear springs for towing.

How much tongue weight does this camper have when loaded? How much does the camper weigh all together? What else do you have in the car? How many people ride with you? How many miles on the car? Have the rear shocks ever been replaced?

The load leveling system should help out as much as any air lift system. It is very possible the rear shocks are worn out, or there may be an air leak in the system also, which those appear worst when there is a heavy load. If you are trying to take on more weight than a properly working leveling system can handle on the rear, you are likely overloading the axle all together.

There was. I think it was clm2112, in a 88-91 LE with no load leveling.

something like this would work...You will have to probably do a little fab work... I would probaby do a manual fill valve for them so you can manually adjust height:

You can get clever with the inflation valves as well.. Seen this alot, used to hold rear plate on. Then you can use a air hose from your air valve on the OEM leveling kit to fill the bags on the plate.. except i would do one valve and tie both bags together so they stay ballanced Left and right.

Actually I'd leave them separate, otherwise they can contribute to body roll, instead of helping it, because as one compresses, it puts air into the other side, causing it to push the side on the inside of the corner up, instead of helping keep the outside side up...
