I now do the same thing, and shut one tank off completely. Mine also has that little glass indicator window but its hard to see the color inside, plus, you need to remove the big tank cover to look at it. So far has worked out well.

On my 2006 TT, its LP T-valve is 100% manual.
When one tank runs out, a person must manually move valve pointer to other tank.
Best to read your TT's manual...
Mine has a manual switch, either pointed to one or the other tank, or in the middle, which in the middle when a tank runs out it pulls from the other. Tend to keep it on one, so I know when one runs out, I switch it and then get the empty filled... If you keep it in the middle, you might run both out, at a bad time.
