To update everyone and hopefully help someone in the future, almost everyone with a magnum 8 airbag chassis probably uses the Koni 8805 1004 SP1 shock as their front shock and the Koni 8805 1005 SP1 as the rear.
But if your front shock has a threaded stud on top and horizontal bushing on the bottom, it may well be a Monroe 65444, Also known as a Monroe Gas-Magnum 65. According to the data sheet this shock was designed for trucks using air springs and tapered leaf suspensions.
It appears that at least a few coaches were made this way, but not many. I think Beaver, or Safari might have been experimenting to see if it improved the ride since my mounts all seem to be original. My shocks were also painted with a black strip up and down the shock that helped obscure the Monroe stamp and the numbers. Since the shocks look original I am thinking the factory might have done this to make them easier to identify. I can not think of any other reason someone would spray paint a 2+ inch wide stripe on the front of the shocks and nothing else including the rear shocks. For me it took a lot of scrubbing and cell phone camera manipulation to capture the Monroe and the 65444.
Anyway, I found some of the shocks and ordered them. Thanks to everyone who has helped with this issue here, as well as Koni NA, Braswells RV, and SuperSteer who graciously took the time to look up shocks and answer my questions.
