Propane gauges on tanks question
Trailer is 2013 and the propane "sight level gauge indicator" doesn't work right. Supposed to be "green" when enough propane is in tank then turn "red" when tank is empty. Then the turn knob and use...

There is nothing wrong with your gauge, It is one of several issues (I will list) including the ever popular OPERATOR ERROR. but frankly that is not #1.
Here is how it is supposed to work,, The gauge shown above will NOT work on a dual tank RV properly (Ok 2 of them will) I grew up with this kind of gauge so I have experience with it.
The Regulator shown above is in two parts, The top is the KNOB, which is a valve and "Pre-Regulator" The valve should "Select" one of the tanks and apply near full pressure (around 100 PSI) to the regulator below which then regulates to the proper pressure for your appliances.
When the selected tank can no longer supply the pressure (When it's empty) then the valve is supposed to apply a lower pressure from the back up tank. HOWEVER it has failed in that and is no longer working properly
The gauge by the way is connected between the top and bottom (Between the valve and the regulator) even if it is connected to say the top of the valve (The connection to the regulator side is internal)
Two solutions:
One: Close the tank vale on the back up tank and when the primary runs dry, Close the valve on it and open the back up tank valve making it the new primary, DO turn the valve over just for fun.
One of the other functions of that change over valve (This may or may not still work so CAUTION, is a check valve allowing you to remove the empty tank.
Solution 2: Replace change over valve.
