Just count clicks when you move the selector.
Alright.
I nominate this answer as THE MOST STUPID EVER!
Your gear indicator is just as important to have working CORRECTLY as say the brakes.
What if SOMEONE ELSE like a spouse, son, daughter needs to move the RV?
Perhaps the BETTER answer would be seek out a mechanic or perhaps get the service manual for the chassis?
But really posting drivel about counting is not the "fix".
To the OP, If I remember correctly the indicator is operated via a cable. Most likely the cable broke, or is hung up or even has disconnected from one end or the other. Really hard to diagnose via 'net. This is why a service manual would be helpful.
I wish I could help more but I have never had this issue...
