I live in Las Vegas. I have a gas BBQ . Rather than keeping next to my house on my rear patio. I have it next to the brick fence on the opposite side of the patio so that the smoke does not darken the slats on my patio cover. i have a gas hookup that I have not used. ( It would take approx 15 - 20 feet of line to rig up a system to use my gas hookup) The Propane works fine for my purpose. I would like to have a spare tank but don't want to keep it in my garage or just out in the sun. My BBQ has room to have an extra tank in the cabinet underneath next to the operational tank. I think about this too much and would welcome any suggestions. Thanks in advance.
