Little update on the Alu-Cab shadow awning install on my Frontrunner roof rack. After about a week I noticed some loud and consistent squeaking from two slats that were to the left and right of the front awning mount.
Due to the way Frontrunner slats are are mounted (via a bolt from the bottom, and not all the way through the side rail)... the weight of the awning pulls the top of sidewall outwards, creating a loud creaking noise and possible sheer point.
My buddy who is an aeronautical engineer took a look at it, and recommended additional brackets be added to support the Alu-Cab bracket. Since he’s also a welder lol, he decided to build a support bracket on the Alu-Cab mount side and the far mount side. Loud squeaking noise gone and the bracket won’t budge no matter how much force you put on it.
