From the '19 Flying Cloud owner's manual:
"The furnace on Flying Cloud models, excluding the
20 ft. model, is ducted to provide heat to tanks and
plumbing to prevent freezing."
I had a Bigfoot 25' four-seasons trailer for nine years with the furnace ducted to the tanks. While you'll be fine while parked, I would caveat the owner's manual information with that the furnace will likely not be able to keep up with freezing temps while actually driving. It may do fine while you're parked, but if you're travelling in sub-freezing temps, even with the furnace on, you may experience frozen plumbing; and of course the colder the temps, the greater the odds of your plumbing to freeze.
The
only safe way to do extended travel in sub-freezing temperatures is to winterize your plumbing. Any other "solution" may or may not work. And remember, the things most likely to break from freezing are your water pump, faucet bodies, and toilet flush valves. The pex plumbing is pretty tough... those items are quite fragile.
