Hello!
Could anyone tell me why when I first start my bus, it only airs up on the left?  As soon as I move it, it seems to level out.

I would start with replacing the right rear leveling valve.

How often did the coach move before you got it, how often does it move now? How far do you go when it is aired up?

Suspension movement points can get stuck, moving the coach provides the shock to unstick them.

Hard to hear, but any air leaks noticeable while this is going on?

I don't like working on stuff, and i hate working on stuff that isn't really broken.

Air the coach up and go for a drive several days in a row, get that bus hoppping up and down regularly, see if it goes away by itself?

If you lea ve grand dad sitting in his chair too long, he has trouble getting up too...

Happy coaching!

Has anybody come up with a good plan yet to use the air ride for leveling the coach when parked? It's on my list but there are so many things that I hope someone else will do it first. Something simple with minimal electrics would be nice. I've been thinking mercury switches and maybe a relay or three.

I saw it on the Internet. It MUST be true...

Yes just copy HWH Active Air Leveling using toggle switches instead of the touch pad and controller board  and be done with it

We can manually level our 4104 when on uneven ground using the original leveling valves. For under $80 & a days work using four 12 vdc air solenoid valves.with controlling toggle switches at the driver. We love it. Saves a lot of block leveling.

Hello and thank you for the thoughtful response.  The bus sat for many years before I revived it a month ago and drove it home 900 miles. 
I don't hear any leaks.
I'm leaning toward replacing the leveling valves in the rear.  Jist have to find the time to block this thing up and get it done...
