DR Jennifer - I think it was DR Jennifer - Checking the level of your propane is actually quite easy to do. Since the propane gas is in liquid form in the tank, it's very cold. So, to check the level in the tank just pour a cup of hot water down one side of the tank. After a few seconds, just place your hands on the tank, and when you feel the metal go from warm to cool/cold, that's where the level is. There are even temp strips that you can affix to the side of your tank that "colorize" the level.
