2020 303 RLS no heat in bedroom found problem!

Just wanted to share. I found out why I had no heat to underbelly or front bedroom. Duct hose was just taped on with aluminum tape and fell off. Fixed with self tapping screws and resealed with new tape and now i have heat. Other models may have this problem as well.

Ours did the same thing and I fixed it the same way. I also found a loose connection on the furnace which is near by.
Good post and pics , which I did not take any when I fixed mine.

This same thing happened to our 2015 303 . . . it is amazing how long this has been happening (and how often it has been reported to Grand Design).
