The Brustor window awning has two Achilles heel issues: the roller rotates inside a fragile nylon retainer on the non-motorized end. That fixture requires periodic inspection. The clamshell cover that must be lifted to inspect the awning for security is held in place by two tiny countersunk stainless screws which are prone to falling out (the second weakness). Once that cover extends to 30 degrees or so, it is designed to exit the scene. Were it to remain momentarily thanks to the remaining tiny screw, it could mar extensively the side of the coach before fluttering off into the windshield of a passing motorist... A curious and weak design, indeed.
