[QUOTE=youroo;269903]The extruded fixed rails aginst the side surface of smooth sided units have NO movement and NO gaps. If movement or gaps are present the fastners are defective or delamination is present. Youroo!!
I went to the local RV dealership and every unit there had a gap like mine. I guess I just never noticed it. I went to the sales dept and asked if I could run a couple units awning out and everyone I did the channels flexed like mine. I guess it is normal. Still doesn't seem right to me. I am sure that I am not having delam issues.
