Please excuse me, this is my first RV, so all this is new to me. There are two of these on the outboard bottom edge of my Slideout. When I first saw them I assumed they were for attaching supports. But everything I see says not to use supports, for a variety of reasons that all make sense…fine. So if that is what they are, why would a MFG put them there, and if that’s not what they are for, what are they?
The rust marks on the plate area appears as if they have been adjusted quite a bit.
They are on a 2009 Keystone Springdale.
