Propane question
My fifth wheel has two tanks like most, if I put the knob in the middle and not right or left will it choose the full tank when the other goes empty?

At 0 degF it has a pressure of 24 psig, which is well above the 11 in of water column that is required to operate the appliances in an RV.
As the propane boils off inside the cylinder there is a cooling effect and heat needs to be absorbed from the outside. With low volume this heat transfer slows down (see diagram posted earlier). I believe it would be easy for the liquid propane to be 10 to 20+ degrees below ambient during heavy usage and low in the cylinder.
