I wanted to make sure all gauges meant all gauges--some times people give incorrect or incomplete info.  The only way all gauges can read zero, have no air in the 3 gallon air tank in the RR wheelwell is if a check valve has been installed AFTER your front slide seal regulator.  My coach is not built that way.  If my RR wheelwell tank goes to zero pressure both of my slide seals deflate.

I see....but wouldn't a check valve prevent the seal from deflating on command when the HWH key is engaged to move the slide ?

The concern on my part is that if the coach is stored with slides closed and no power to maintain the 12V compressor, the seals will all deflate then and allow water to get in (potentially) as the coach sits outside during a heavy rain or storm.....right ?

I need to figure out a way to keep those seals inflated with zero power and zero air after a while.....if it is even possible.....
