Another issue that comes to mind: how much propane can you put in an empty tank??
One who knew nothing about propane would assume that if one has a 40 gallon tank, one could fill it with 40 gallons of propane. Right? NO, WRONG!!
How much propane may be placed in the tank is a function of the ambient temperature. This you find out when you have the tank filled with propane.
This may explain my previous post where I mentioned that we got less than 4 MPH on propane, but could not get 100 miles from a 40 gallon tank. You cannot put 40 gallons of propane in a 40 gallon tank!!!
