The Gen-turi Suction Cup Mounts are designed to quickly secure your Gen-turi exhaust system to your RV with the twist of a knob, and keep it there until you're ready for it to come down. With the suction cup mounts, there is no need for drilling holes in your RV or potentially damaging the exterior. The suction cups can be removed at any moment and can go with you if you ever decide to move RVs.
