first, the Excursion is made by Fleetwood, not Forest River.
so, i seriously doubt that anyone here(since nearly all own FR products)would know anything about what you're asking about.
suggest you see if there is a comparable Fleetwood owners forum.
if you need general help with RVs and their operation and systems, you'll get plenty of help here.
but questions regarding a non-FR brand or model, will probably not get answered.
