The Universal Outdoor RV Ladder can fit on the rear of any RV, straight or contoured. The rugged construction keeps you safe when going up to do maintenance on the roof or just hanging your chairs on the ladder as you travel to the next camp site. The ladder is designed to be cut to length, fitting perfectly on the back of your RV. Please refer to the installation and measurement guide to properly install your Universal RV Ladder. The ladder comes with four stand offs and mounting hardware.
