Propane High Pressure Regulator Leak.
On my Jayco 5th wheel with an auto change regulator and both tanks open, what is there to prevent the full tank filling the less than full tank. I just changed my auto regulator since the old one was ...

Any LP Reg that leaks from vent hole has failed......diaphragm is cracked/torn etc
Vents are on the 'atmosphere side of regulator diaphragms
Roadside regulator (30#) is used to lower pressure from roadside cylinder prior to going across front cap of 5th wheel and to prevent the propane vapor from condensing into liquid propane which will destroy the auto changeover reg on curbside
Curbside cylinder pressure can be 250#.....auto changeover regulator is designed to handle high pressure in 1st stage reducing it to 15# which 2nd stage then reduces to system pressure of 11" WC (0.4 psi)
Indicator knob/lever -----point it to cylinder you want as 'primary' then other cylinder is 'reserve'--Valve in both cylinders.
When primary pressure drops to 10# the regulator will swap to reserve. Red/Green Indicator will turn RED....move indicator knob/lever so it points to 'reserve' cylinder. Indicator turns Green
Do NOT point knob/lever between--pointed down -----should point to one or other cylinder
Built in check valves SHOULD prevent any backflow from one cylinder to other
