The Camco RV Gen-Turi Generator Exhaust Venting System helps reduce noise and keep the air fresh at RV rallies, campgrounds, and tailgate parties. This system allows you to vent offensive and unhealthy exhaust fumes from the top of your RV instead of at ground level where they might be inhaled by others. This system is easy to install and disconnects quickly, and weighs only nine pounds.Expires Dec 20, 2010
