Yes Richard the original issue was the tag. The gage would show the pressure I always had it at but when coming to a stop the tire would chirp which it didn't do before. So it would seem that the system would look like it was working but may not have been. A couple days ago while parked for a few days I loosened and retightened the solenoid and tapped on them and to my surprise everything seems to be working fine. Even the air pressure dropping while traveling. I do have an Inficon leak detector but unless you are in a building or have a very still day it won't work as it picks up the smallest draft. Soapy water has picked up leaks the Inficon didn't.
I have posted a picture of the Solenoids on this thread, page 1.
Traveling now, will be at Camp Newell Today for Monday apt to resolve last summers issue then continue on to our winter spot in the desert at Imperial Dam Recreation area just north of Yuma AZ. The coach had been weighed a few years ago and all was well then.
Seems my last few air leaks were most likely related to debris in the system. As Foliver mentioned earlier, perhaps filters placed inline before these solenoids would help.....

Thanks for everyones help.
