You might check the expiration date on the propane cylinders as well. I'm at the office now (otherwise I'd run out and check) but I believe that propane cylinders are stamped with expiry dates after which they can't be refilled. I don't know if they can be tested and recertified or if they need to be replaced. Some years ago tanks were required to have overfill protection devices and those valves have a distinctive triangular handle. I'm not sure when those went into effect but if your TM has the vertical tanks, it could very well be that the owner has rotated the TM tanks with his barbecue grill tanks. - Camp2Canoe
