CDM, have you sprayed a soapy  solution around you LR bladder to check for a leak?

Yes,  I have sprayed soapy solution on the bladder when it is under pressure and do not see any signs of leakage. I am at point where I will let the service people take over. I will leave the air to the bladder shut off at the valve at the vacuum generator. I do appreciate everyone's input

Be aware - if you have extended the slide and shut off the 1/4 turn valve to its bladder, you will not be able to retract the slide.  That valve needs to be open (on a 2003) to satisfy the vacuum sense that "trips the bit" that allows the slide to be moved.  To retract the slide you will need to clamp the slide line shut with something like vice grips then open that valve and allow the vacuum generator to cycle.  Then close the valve again once the slide is fully in.

And yes, the 1/4 turn OEM valves are notorious for leaking and brass quarter turn replacements are recommended.

To drive with a bad slide bladder, we like round closed cell insulation tubing (aka backer rod) to fill the gap and low-tack duct tape covering over the gap.
