It's about to get cold....

I called Fleetwood. They said the tanks are heated by the furnace. They also said that the storage bays are insulated and should be good until it gets below 0. That seems a little low, don't you think?

Make sure the dripping faucet drains into the grey tank. Some RVs have the bath vanity plumbed into the black water tank.

100 Watt light bulbs is the ticket IMHO also. And leaving the cabinet doors open too will make a huge difference. Good luck.

My Winnebago Vista had an open area under the bed that allowed heat from inside to move to the wet bays.

If there's a furnace duct going to the holding tank bay, you might be able to see it. Mine looks something like a vacuum cleaner hose end sticking through the ceiling of the bay.

I would rather doubt that you'd have no heat in the holding tank bay given that it's enclosed and the rig otherwise seems to be built to at least basic winter operation standards (i.e. the pipework is within the heated envelope of the RV, etc.)

If you are on hookups, I don't run my propane furnaces during the day; I use electric space heaters....saves on propane refills and $$. My rig has three separate heater vents going to the holding tank and storage bay areas, so running my propane furnace at night keeps these from freezing. The bay doors also have about 1 1/2 inches of styrofoam insulation, which helps.

I also open all my under-sink cabinets at night to let heat in there to keep those pipes from freezing.

Last year, my ice-maker valve froze and cracked spilling water everywhere under the fridge when it thawed out. I now turn off the water to the ice-maker and disconnect the line to the valve to bleed off the water inside, then reconnect. I only do this if the temps will dip below 20 deg F.

Some caged 100 watt drop lights in those bays should keep things from hard freezing.
