Should the awning rail be one solid piece? The back end of the rail on our 2018 M25 is an added section approx. 2 ft long. Use of the awning is causing that added section to pull away from the sidewall. I have a photo if you'd like.
I have a 2018 M28 that pulled away as well first time we used the awning. Quick 30 minute repair and I was told that sometimes they make the holes to big at the factory or just plain strip them out. Fixed it with something similar to a toggle bolt at Camping World. Works great now.
