Try "RV Factory Surplus" or "Pelland Enterprises". I have read on this forum that Forest River will not sell direct to customer but have not tried to order anything from them. Give them a call and see what they say.
I need to take a closer look.
Surely theye is some sort of seal that prevents water from entering when the slide is closed.
I will report back with my findings.
Thanks for the responses.
