Has anyone done much winter camping with the 2108? Just got ours and wanted to know if it stayed comfortable in sub freezing temps?

We were close to freezing late last fall in the Adirondack mtns in NY. Heater ran quite a bit all night long, was ok, but think it stressed the heater a bit.

Thank you for responding! That's good to hear. I will use a space heater for additional heat. Wondering about the pipes freezing. They are enclosed with a "heater", but I wonder how cold they can really get.

 

[Wmlunt-WO]

Space heaters use a ton of amperage, be sure you don’t overload the electrical circuit! The propane heater kept up, I suggest turning the a/c fan (the one on the thermostat) off when running in heat mode. The heater fan on the furnace runs as needed.
PS I cracked open the doors to the cabinets that had piping.

 

[Madoc Rhys]

Great points/advice. Thanks!

We tried a ceramic space heater on our last trip. Worked great. When we got up we plugged the coffee maker in and when we turned it on, the breaker immediately tripped. FLX has a 15 amp breaker for all (7) the AC outlets. The 1500 watt heater draws about 12 amps.

 

[Madoc Rhys]

Got it. Thank you. Much appreciated.

The furnaces in campers are designed to not run continuously. The fan will keep running but the gas valve will cut out because there is a snap disc thermostat/breaker in the safety loop that stops the flow of gas. It cools down and resets and the gas flows again. They are designed to cut out around 5 to 6 times per hour. You will not strain the furnace by running it.

We use electric because in the past the furnaces were so loud. My wife hated them. The new old WInnie has a nice quite furnace but if I was plugged in I would run an electric set on low and let the furnace run some to keep the underbelly areas heated for the pipes.

 

[ChrisRiley]

The reason we tried the ceramic space heater was the furnace is quite loud. We're very light sleepers and the space heater is very quiet. If we're not plugged into shore power, then the furnace is a must.

OP’s trailer is a Micro 2108, the furnace does not heat the underbelly, there are heating pads on the 3 tanks below, obviously you will need to run those in addition to the furnace,

Well, I went and looked up the 2108TB. Under heating and cooling it only lists the AC unit. The Comfort tech package mentions insulated heat ducting. The Explorer package mentions propane heating.
The layout of all the packages is identical so far as where the water is routed. In the photo on the Winnebago site I can see an exhaust port under the refrigerator access panel. This does not tell me if it is ducted in the floor of just distributed with a couple of flex lines and ports. Without actually seeing this unit I could not tell you what is best for it.

 

[Wmlunt-WO]

The port under the refrigerator is indeed an exhaust port for the furnace unit. There is a port inside under the refrigerator that has an intake for cold air, and outlet for the heated air into the trailer. There are no floor vents at all in the trailer. It is a self contained unit and I don’t believe it offers any heating to the underbelly where the 3 water tanks are, they have pad heaters, likely little heat goes into the underbelly section, maybe enough to keep the piping below a bit warm.
That lower section is enclosed with coroplast, not really thermally insulated. Comfort tech package description may be for RV, as opposed to TT. Considered a 3 season trailer.

I have a 2022 2108 DS that has been used in multiple nights in the 20s. I have added insulation around all the pipes I could see under the kitchen and bathroom sink. When it is that cold, I went through a propane tank in about 6 days. I had the temp set for 55 during the day and at night I went up to 64. Then back down to 57 for sleeping. I will be spending this Christmas on the South Rim of the Grand Canyon. It looks like lows will be in the 30s (very warm). In cold weather you need to keep a fan going at night to pull moisture out. The first thing I did was change out the cheap fans for two Max Air fans with covers. They are controlled by remotes and setting from 1 to 10. Fantastic Fans are also great. I have found without the fan pulling moisture out, you wake up to windows and the interior moist. I have never used anything but the installed heating. I see no reason the get any type of alternative heating unless you do not have access to refilling propane.

 

[Madoc Rhys]

Thank you all for your responses. I will do some testing and report back. I think I have heater pads underneath and then a non-ducted furnace.

 

[Wmlunt-WO]

Best of luck! And let us know how it turns out for you!
Your statement is correct on tank heater pads and non-ducted furnace. As suggested, I crack open the exterior vents to reduce moisture. I used the hengs variable speed reversible fans as I did not have to replace any of the sealed parts of the vent on the roof, retro was ez-peasy. One pushing and one pulling works gear for stove and shower use!

Let’s answer this question first.

No, your Micro Minnie is not designed, insulated nor protected for extended winter temperatures. Period. (And you will find this to be true in seriously hot 100 degree summer temps as well.)

Not only is there little insulation, but significant air leaks in all RVs. Will you do fine for occasional cold weather? Sure. But your RV is a 3-season habitat, at best, and not intended for freezing winter temps. If the winter you are meaning is a cold spell, even a freeze, in Florida, Texas And Arizona you’re good. But if you’re asking about winter in Massachusetts, Ohio or Montana then absolutely not.

And running a heater or having heated tanks will not “keep your pipes from freezing” in prolonged, consistent temps below 29 degrees. A day or two, yes, but many days in a row, no.

It’s impossible for us to know where you want to be in your TT in the winter, how cold it will be or how long a duration you are asking about. But the answer to your initial question is. No, you will not be “comfortable” in freezing temperatures in your Micro Minnie travel trailer.

I have a catalytic heater run by a propane bottle I have used for tent camping as it was deemed safe for using inside a tent. I wonder it that would work as an additional form of heat?

Got it. I just prefer to camp in colder weather. Less crowded etc. Probably not multiple sub-freezing days (I’m in the south) but definitely some colder temps. We’ll check it out. I’m grateful for all of the replies!

While living in northern Vermont we used a KeroSun high efficiency kerosene heater. We did have low oxygen which lead to a lot of arguments. Eventually I had to crack a window or door to get the air needed for combustion, kinda offset any heating savings, but an all electric townhouse up north just doesn’t work.
SO thought I was crazy to open a window in winter…
