Hi, does your new 2020 use the Firefly multiplex control system? Sounds like it might have some common control system that goes berserk. There have been some problems with the newer software/firmware on the Firefly systems noted on the Forum a few weeks ago, where systems (including slides) would start moving on their own. As you can imagine this is very dangerous.
I think that older version Firefly software/firmware had no issues and that Firefly had corrected their problems with the newer software and were working with Thor to install the corrected software/firmware. I am not sure if this is your problem, but I would call Thor and Firefly to see if your coach is a likely candidate.
