A Royale has little if any converter air. I think the generator air bags and maybe the driver seat so checking the conversion part is going to be simple. Plug each one, one at a time and see if the air loss slows down.

The chassis however from anecdotal evidence for that vintage has some areas I would focus on. The first would be the belt tensioners and the regulator. I would take a hard look at the regulator and fittings at the rear of the small compartment behind the tag axle. They are almost impossible to see, but they are there.

I would check the small air lines or fittings at the rear of the air system gauges.

Then there is everything else.

As far as the brake system, when the coach is parked all brake system air losses are going to be from the relay valves, air tank drains, or the foot treadle and all associated protection valves, check valves and fittings. My guess is the relay valves or the foot treadle.

I think on that year the gen air bags will be manual fill , I think the gauges will be 1/8 lines you can get comp fittings for them and the ones in the steering compartment change at both ends to comp fittings

Reply: I love these first palces to check because of their accessability. I should be able to hear this leak becuase of how fast it’s going down.

I will also check the gauges.

I guess Peter is saying that my 97 has a number of these “push” fittings that I read members saying should be converted to compression fittings ?

Yes on my Gen air bags being manual fill. I need to order an air bag. I put an inquiry for where to find these on the Generator topic.

Peter is correct regarding issues with the push in fittings but if you are looking for likely trouble areas start with the ones that seem to have been mentioned most frequently. If I failed to say so, seats are notorious for leaks at the valves especially.

But all of us who have coaches with push in fittings instead of compression fittings are going to be victims of the effects of aging on those fittings. Compression fittings being metal to metal are unaffected by age so if you intend to replace fittings you see leaking, try to use compression fittings.
