ken,
the air port in the rear should not be leaking. like all couplers they hold the air in until you put the air hose or mail fitting in.
a picture would help us of what your setup is. on my 99 it didnt have an air port but the line was there and capped off so i added a shop air port.
some coaches have the air doubler plumbed in as well and that should be valved off when not using.
i pretty much only use prevost non whipping couplers in my shop and coach nowadays. pricey but really nice
