You are correct that the Atwood 85841 master cylinder that you referenced has been discontinued since Atwood's acquisition. There are not any direct replacement parts that are compatible at this time. Since Atwood is no longer in the actuator business if you swap out your whole actuator it eliminates the hassle of finding replacement parts that will become harder and harder to find.

The Demco Hydraulic Trailer Brake Actuator # DM72VR is your best option to replace the entire coupler. The Demco actuator is made of a sturdy, corrosion-resistant construction and includes a larger master cylinder has a 20% larger cylinder for more fluid supply. Included is a video resource for additional information.
