It will never cease to amaze me as to the inteligence of the people on iRV2.
I read a while back about how to check the amount of propane you have in a stationary tank in the storage area.
It basicly said "pour hot water down the side of the tank, then run your hand down the side until you feel cold, that will be the level of propane in the tank"
I've been procrastanating and doubtful if it would work, so today in 24 degree cold I figured I would put it to the test.
IT WORKS!! (I hope)
