So I have been thinking a bit about airbags especially the drive axle air bags. I noticed that my coach tends to lean and sway quite a bit and I think it’s also part of the reason the coach tends to wander when going down the road. I know there are other potential issues for wandering so do not want to get sidetracked on those for this discussion. 

So my thoughts are that the ping tanks with the large line going to the axle may be contributing to the excess lean. So my rationale is as follows, because the air is not limited to what is in the bag but also the volume in the tank, now you have more volume that can be compressed. I think this is allowing the coach to lean more by compressing the increased volume. Question I have is for those folks that have done away with the large line bags and have gone to the smaller line bags do they notice any lean difference?

Another factor that I am sure affects things is my coach is a hump back coach so the center of gravity may be higher. 

So I may end up doing an experiment by using some reducing fittings and running smaller lines to my drive axle air bags direct, get rid of the ping tanks and use the smaller fill line. See if this improves the lean and hopefully also improves it when driving down the road which would also help a bit with wander possibly. 

Just some musings to keep my mind busy while I have a thousand other things I am trying to get done.
