Propane regulator

This may be an odd question, but does the auto changeover regulator have to be facing the trailer so it's hard to see? I turned mine around and now doesn't show when tank is empty? It was working until I turned it.

Did you turn the handle toward the appropriate tank?

Direction does not matter. What brand of regulator is it, or post a pic of it.

It was working until I turned it.

While physical location doesn't matter, the proper connections do matter. After many years of a career fixing things, I have learned that when something that works stops working after I worked on it, the problem is usually something that I did. To change the regulator location the supply hoses will need to be rerouted but the connections should be exactly the same as they were when it was working.

As long as BOTH propane tank valves are open, the regulator should provide propane to the RV. The regulator needs propane pressure to slide its valve that selects which tank to use. If you only have one tank valve open and depending on which regulator port it is attached, the regulator may not be able to use the tank you have open. Given that you reversed the ports relative to the fixed tank locations, you likely also needed to reverse which tank you now have open...assuming you only keep one tank open at any given time like many of us do to avoid never getting the surprise of emptying BOTH tanks.

The other potential issue is that small propane tanks also have a safety feature that closes a valve for a short period if the flow rate exceeds their limit. This could happen if you quickly and fully open a tank valve into the empty line feeding the regulator.

Both tanks were open, and both tanks ended up empty, but
didn’t show either as empty.

What was the purpose or turning the regulator 180°? Every one I've owned was easily read, it had a green band and red band. When a cylinder was empty the lack of pressure allowed the green band to descend out of sight and the red band appeared.
I suggest doing as Kirk recommended and putting it back to the original position. While performing that task, snap a picture of connections first, then afterwards. It it then works after reverting to the original orientation, you're sure you didn't make a mistake.
A propane cylinder will have the same internal pressure until it's nearly empty, then a gauge will change quickly.
