I read with interest your post concerniny M-10 updates. Our dealer (TVRV, Elkhart IN) failed to discuss many items, the M-10Magadyne Radio being one item overlooked. We purchased a 2018 XL40B. One item I am quite proud of is my iPhone app that lets me turn lights on-off, move slides open or closed as well as the awnings. Precision Plex wireless app is freely qavailable at the Apple App Store. Another group, available on FB is the Berkshire Motorhome Owners Group. Good info on these coaches!
