Stop lugging around that extra propane tank. Now you can connect your Camp Chef cooking system directly to your RVs propane. No need to take up space with a separate tank for your cooking system. Simply attach your Camp Chef cooking system to your RVs propane directly with this 8 foot connection hose. Excludes Mountain Series cooking systems. Note: Most RVs built after 2004 come equipped with a quick disconnect with shut off. RV owners whose 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.
