"No bungee cords, no seat belts, refilling or exchanging a propane tank is no longer the dreaded chore." EZGO has "feet" in the four corners, these feet grip the ground to ensure a propane tank stays upright and secure during transportation, storage and use during camping, tailgating, and backyard BBQs. EZGO also keeps a tank off the ground, so the "rusty ring" is greatly prevented, which helps protect carports, decks, or patios from any damage.
