I often spent the night in sleeper when well below 20* Heated mattress pad and blankets, I sleep fine. (when outside temp gets below 0 F would worry about the Cat cranking back up) But when it's below freezing in the sleeper it's a looong way from the covers to the starter button.
I had a small, (300 W?) inverter. I would plug a heat lamp into that, inverter into a switched 12 V lighter plug, then clamp the lamp where it would shine on me while I was getting dressed.

While I've camped in temps down to the upper teens, I think I'd be fine down to temps near 0.
Like many, my FW was advertised as 4-season. I was impressed, with the thought that went into the design. First thing, everything is very well insulated, noticeably quiet inside, in a busy RV park.
The heat ducts, from the furnace, are next to the waterlines through the various cupboards, and exit above the floor. Other heat ducts run under the floor, still next to water lines, with one duct right next to water pump.
The entire basement, with all tanks enclosed, is heated and well insulated. Even the baggage doors are insulated. All flooring has Refectix insulation on the underside, even in the baggage area under the bed.
After tenting a number of years, this is my 4th RV. It is a Yellowstone brand, which at time I purchased new, was the high end division of Gulf Stream, and built in it's own separate factory. No complaints, most things about this unit were better than expected, when comparing to previous RVs I owned. ![[emoticon]](https://forums.motorhome.com/sharedcontent/cfb/images/smile.gif "smile")

LOW of 27? I wouldn't worry about anything freezing overnight. If you are hooked up to power, I prefer to use electric heaters rather than burning propane. Propane is loud, expensive and puts out moisture.
Daytime temps should keep things from freezing.

A propane furnace does not put moisture into the trailer. The oven and stove do, but not the refrigerator or furnace. Moisture is one of the products of the combustion of propane with oxygen. This combustion occurs outside of the trailer, otherwise there would be a very high risk of carbon monoxide poisoning, another product of combustion. There is a heat exchanger that takes the heat from the combustion, without letting any of the combustion components, including water, in. The heat from the heat exchanger then warms the trailer.
The moisture inside the trailer that you see comes primarily from your breath, which is FULL of moisture. If you cook inside the trailer, some moisture comes from that, but it is primarily your breath. Oh, and if you take a hot shower, but that one should be obvious.

Portable unvented catalytic propane heater does put out moisture.

Notice that I was addressing the TRAILER'S furnace. You can definitely carry things INTO the trailer that put out moisture. An unvented catalytic propane heater is one, or anything burning propane that has the combustion chamber inside the trailer. A humidifier is another. If you want to address separate purchases that can do that. The number of OTHER THINGS you can carry into the trailer is large, so I limited myself to factory appliances.
And, I stand by my previous post.

Well a contractor was using a catalytic heater in trailer to keep supplies from freezing. I was doing some repairs on equipment on jobsite, and every time I walked in that trailer glasses would fog up. If that moisture was all coming from me, the lenses would of fogged outside, cleared in the warmer air.

I'll fully admit that I don't understand how the science of things work... but an electric resistance heater will dry the air and you won't have excessive condensation inside the camper. The propane heater doesn't dry the air and its quite common to have excess condensation inside the trailer.
