On ours, the left side main regulator has a little oblong window that when the tank you are on is empty, a little red flag slides up and the window becomes red.
Option list suggestion.
Have WiFi Ranger as an option. Here's a link to the other manufactures that have it. I just ordered the RV Pack TI. and the Wison Sleek for the phones
