Having water in any rv below zero becomes iffy . We run into 'cold spots' where a freeze can occur. Each rv is different , it all depends how the drains and water lines run. Each unit must be addressed individually.
What I found when I owned an AF .
You are better off keeping the slide closed at night and just using the furnace, due to the design of the basement heating system. There is also a fan mod you can make to improve heat flow.
You can simply move the fan closer to the edge of the wood frame.
(under the bath, remove the round plastic vent and look at the fan) As you see, the OEM position is recessed a bit. After you move it closer to the round plastic vent opening, the warm air-flow improves.
The improved fan mod below the bathroom door should work well enough to improve heat flow under the cabinets without opening the need to open doors.
If you would test the air flow at the return outlet (kitchen sink area) before and after the mod, you will see how the air flow increases. Simply use a clicky lighter and look at the flame. It bend at a 90' angle after the mod.
As stated by other cold temp posters, there are going to be some hit n miss spots in every camper and it might take a few trips to weed it all out.
***Something you should do when camping in cold weather is, cover/insulate the regulator changeover valve on the propane tanks. If that diaphragm cracks , its not going to work , gas flow stops .
It can sometimes just freeze and all you have to do is thaw it using a hairdryer.
Since I started to insulate it , I've not had any problems and I use my tc furnace down to -30F .
There are a lot of good 'insulation posts' out there. The 'projects' section will show you some. Here is one .
