Our trip is not starting out well. First the blown coolant line in northern California (now fixed, see previous post.) Now we have a leveling issue, fortunately this is a problem, but not trip stopper. A night ago we heard a very short high air pressure hiss - presumably a line or connection blew or released. I have not been able to locate it. However we can't stay level on either our air or hydraulic system. There does not to be any issue while driving. We can initially get level on the air system, but we are quickly listing to the right with the compressor running regularly for 3-4 minutes at a time (but having no effect on our list.) Using the hydraulic jacks also doesn't work. We are initially level, but fairly quickly start to list. What I've identified is that when the jacks are down, the passenger side and driver's front air bags are dumped, but the rear driver's air bags are holding air and causing us to tilt. I tried manually dumping the rear bags and got back close to level, but the bags appeared to re-fill and put us back right where we started. The air bags should be good, they are only a year old. Any suggestions? We will be in Bend tomorrow and I was thinking of seeing if Beaver Coach Sales could take a look at it. Or would we be better to divert to Henderson's Line-up?
