Freeze prevention ?

The campground DOES NOT have winterized water connections just above ground faucets. Hopefully they work. The camper is a 2017 Outback 325BH with a fully enclosed underbelly. I’ll assume the underbelly is heated since the camper has a thermal package. Anyone know ?
The unit has an electric fireplace plus the LP furnace. I’m thinking of running the furnace even when we leave for the game and setting it at like 50 degrees. Daytime temps on Saturday are only in the 30’s.
The unit has an outside kitchen with water and that worries me too.
After this weekend I’ll fully winterize the unit and we’ll br8ng it home.
Any suggestions would be greatly appreciated.

It's quite possible the campground has winterized their water lines and won't allow them to be used. You may need to bring containers for transporting water to fill your tank. It's also possible, they have closed their dump site.

Don't assume anything when it comes to heated holding tanks. Various manufacturers used different levels protection. Some just insulated around the tanks, some insulate the tanks and enclose the under belly, some insulate tanks, enclose under belly, and route heating duct work near the tanks, some insulate tanks, enclose under belly, route duct work nearby, and add an opening for heated air to blow on the tanks, and some do various levels mentioned above, plus install electric heating pads on the tanks. They will all tell the customers "they have heated tanks". The "thermal package" could simply be the enclosed under belly.

Also note, even those units with the most extreme tank heat options, won't protect the tanks unless the trailer is plugged into shore power and furnace is running 24/7.

I too, would be concerned about water lines in that outside kitchen. Maybe there's some way to vent some heated air into that area.

I have used my TT (it has electric pads (12/110 volt) on the tanks, enclosed under belly, heat duct running along side the tanks) for deer hunting in North Dakota. On one trip, it got down to minus 5 degrees on the day we were towing back (about 80 miles) to town. Even with the electric tank heat and electric pads on dump lines, down to within 10 inches of the valve. When got to the dump site, my valve was frozen. I had tanks full of warm stuff that I couldn't get rid of. Luckily, I had some disposable pocket warmers and a 12 volt hair drier to thaw it out. I have the plumbing lines disconnected and capped off (inside heated space) for the outside shower.

Bring some RV antifreeze. Enough to pour about half gallon in each black / grey tank, and enough to winterize the trailer if things go sideways with the weather.

If you have a small de-humidifier, bring that to help with condensation inside the trailer. It can get to a point where any clothing that may be touching the walls (in closets and drawers) will get wet. If un-noticed, that can cause mold.

Leave cabinet / closet doors slightly open to allow heated air under the sinks, and for circulation.
