Three replies that have no use to the OP! Amazing!
I like the Marshall brand of changeover valve. Here is a link to one at PPL. Marshall Valve A remote indicator is available that will let you know when you're low on propane and can be read from inside the camper.
Marshall Gas is out of business, and those are no longer available.
The real best would be- in my opinion- either a Fisher or Rego regulator- but they are expensive, and not readily available. The newer version of what you have seems to be good (and what the PPL link steers you to).
I thought the center red dot in the OPs' picture changed from red to green, though I could be wrong.
