From the instructions it’s not clear if the rubber washer is to go on the motothome outside wall or inside wall?
Fiamma are closed today. Either way it would stop the main support plate been mounted flat flush against the body and then also internally the small metal support plate would also not sit flat against the inside wall so for the life of me I can’t work out where that part should go?
The instructions don’t show anywhere in the book a picture with it mounted as a breakdown so it’s hopelsss guess work from me.
