Convenience Panel Question: Grey
I have been trying to figure out what the GRY 2/ AUX button is for on my Convenience Panel. I see a button for both grey tanks to check the level of each. I also have seen others post on the Coachman Owner's FB page asking the same thing. I have a 2019 Coachman Chaparral 298RLS, with 2 grey tanks and 2 drain valves.
Thanks for any info! Pic attached
