I like the idea of the circulator pump. But what stop water from freezing within the individual fixtures? Like the toilet valve or kitchen faucet.
Sounds like others have taken this approach so I assume it can be done.
I have never tried to travel with my water heater on in gas mode.
The same thing that keeps those fixtures from freezing normally, that is, you heat your trailer when it's cold.
Circulating hot water keeps lines from freezing that are run in areas that might not be heated, or not adequately heated.
When I travel in very cold weather 10F and below, I have my propane furnace and hot water heater + water circulation system on all the time.
In my opinion, RVing in very cold conditions is not a time to be frugal. I went through about 60lbs of propane and 15 gallons of gasoline alone for a one month winter road trip running heaters and generators to keep things working and free from freeze damage.
