Stop lugging around that extra propane tank. Now you can connect your Camp Chef cooking system directly to your RV's propane. No need to take up space with a separate tank for your cooking system. Simply attach your Camp Chef cooking system to your RV's propane directly with this 8' connection hose. Note: Most RV's built after 2004 come equipped with a quick disconnect with shut off. RV owners who's RV is without this quick disconnect outlet should consult a professional gas plumber and/or a RV service center before attempting to hook up outdoor gas appliances to your RV. Excludes Mountain Series cooking systems
