As already noted all significant class A coaches have one or more type M female fitting.
The down side of airing your tires is your operating a 350-600 HP compressor to air a tire. I only use it for emergencies and for the most part it has been to air up other folks along the road or in parking lots that needed air. I use my Porter Cable or V-Air if I need to top off which I only do a couple times per year.
As far as the toys go I have a double manual pump and it gives the grand kids some exercise to pump them up.
Since your air governor is going to cut out around 110 and you might have that 50 foot hose attached you are going to have a time topping off tires and will find it really doesn't work well for that purpose.
