Hey, I just wanted to let you know that I also have a 2021 Coachmen Galleria and part of the FB group you spoke of J.S. is the Admin. of all three of the coachmen models. I wanted to let you know which you may already know you can ask the ADMIN in this group to change your USER NAME form and email address to something that want get you a lot of Email....lol Also on another note as I don't know the age of your coach, but if your Li3 or having issues between APP and firefly you may want to get a replacement Vega touch Eclipses Module while it may still be under warranty not doing it could cost about 950.00 yep a shocker for me. Thankfully our 2021 Galleria with Li3. Also you may want to checkout RvXplor.US/ if your wife has a fear of high mountain crossing you may enjoy the website
