Frank, do your flaps remove completely? I think I've seen some that are stitched to the side. Ours remove completely.
Steve mine are permanent.
Sometime after the 09 year Marty made the flaps removable.
FWC did away with them totally . IMO the are a must.
I have PVC that is attached through the bottom of the flap,where the wood stiffener is
that act as supports to hold the flaps like an awning.
Works great for a sun shade and if you want air through the camper while it's raining
they can keep the rain from coming in the window.
Check out some of my camper photos and you will see them.
