Had this same problem a year ago. They only put 2 screws in the stop arm & one had come loose, allowing the awning to come out partially. When I got tp Las Vegas, I put several screws in tha arm's bracket & 1 more screw in the bedroom slideout bracket & all has been well since. It just doesn't make sense to only put 2 screws in there to start with. How much can the labor & the extra screw cost?
