I bought an Inficon ultrasonic leak detector.  It is amazing.  Found several leaks that I would never have located, like the low brake pressure warning switch.  Would have never even known where the thing was.  Pete

Interestingly I didn't get much joy with the Inficon Whisper, I did really well with soap bubbles and lots of patience. My 93 coach has been sitting for 3 weeks or more and still has 40psi showing on the gauge at the rear 6-pack. I'm stunned that this is possible. Apparently it is and I still have a number of original plastic push-on connectors. Even more stunning.

jon, many times my rear 6 pack gauge will not go below 40 even if there is no air pressure.
