The ladder bracket attached to the rear of the RV was not installed into anything structural it was only attached to the RV fiberglass using 4 small screws. When I attempted to climb onto the roof the bracket broke off the RV causing me to fall appx 8-10 to the ground. I was injured as a result of the fall and I needed to go to an Emergency Room for tests and treatment. This ladder is extremely unsafe and will cause bodily harm possibly death to anyone that uses it.
