This may or may not work on your coach.
On older models (like mine) the "tire filler" air connection comes directly off the wet tank, with no check valves to prevent "reverse flow". I can use the double male connector plugged into my air hose and air up my whole coach using a portable air compressor.
On newer coaches, the source of the tire filler hose is usually not directly off the wet tank, but comes from somewhere else in the air system. On these coaches, you cannot pressure up the whole coach air system using the double male connector on the tire hose.
Easy to find out how your coach works - just hook up a portable compressor to the tire filler hose and see what happens. If your dash air gauges show a increase in pressure then you're good to go. If not, you will need to tap into the air system at some other point.
OR, look at your air system diagram and see if it shows the source of the air going to the tire filler connection.
And yes, it is a good idea to have a water filter on the portable compressor if regularly used to air up the coach. But trying it out one time without a water filter won't cause any harm. IMHO
