We discovered before we left that one tank we were using was almost empty & the one we thought was "full" was completely empty. I had a inline gauge (old style fittings) but it really was not useful. I recall seeing stick on magnetic gauges... not sure if they work. I'm not comfortable with the blind "switch over when it runs out" plan.
