OK,that does not compute BECAUSE in Travel mode the right front and left front air bags are tied together pneumatically. That allows the use of one height control valve in the front and most importantly allows the front to float from side to side. The rear air bags via the height control valve on each side control the side to side of the coach while in travel mode.

When you say the right front doesn’t come up:
Does that mean it didn’t raise AT ALL from its lowered position?
Or it didn’t raise as much as the left front? If this, then how much difference from side to side?

To preclude a leaking air bag, hose, ping tank……..if you let the coach sit does the right front drop?

I developed the habit of pressing stop any time while I transitioned from travel to level or level to travel. With key on.
