Awning question 2002 coleman with replacement roof

E, I would add a couple of small screws to secure the awining to the rail, especially before your next trip to the highlands (a.k.a. Colorado).

I've had wind flip the bag up on top of the trailer while driving. I put three 2"x4" pieces of industrial velcro behind the bag to reduce the flip-up. I don't want to know what would have happened without the screws keeping it from sliding in the rail.
