We have been told that our rear air springs on our 1989 Marquis Gillig chassis are looking weathered and we should consider replacing them. We have checked with Gillig and got a quote that was a bit scary. They are Firestone bags which is about all I can see when I check under my rig but wonder if anyone has a part number for Firestone that I could price check on. No one can use the Gillig part number which I do have. I had them checked for leaks and none were found but we have discovered if we leave the air in for a few days the rear end slowly sinks a bit so not too sure what to do about that. We routinely let the air out now when we park it. Any help would be greatly appreciated. We are trying to get everything ready for our first trip South this January.
