Has anyone camped in 15 below F in your CC? I am curious as to how it went. I just did it.

Charles, turn on one or more ceiling exhaust fans on low to help move the humidity out. Run them higher when cooking or in the shower.

Charles, I purchased a dehumidifier, which I use in high humidity and cold climates. This summer on the OR Coast, I was emptying 9-18 pints of water a day to maintain 40-50% RH. In S AZ I could use a humidifier.

This is a great idea, John.  Thank you.  I'd only considered the exhaust fan as Lee suggests, but when we've experienced really cold temps too, I was a bit nervous about leaving one of our exhaust fans open and drawing the air out.

It was 19 degrees here in SC the other night. The Hydronic heater did its job very well. In the past, I had issues with moisture on all of the windows and some of the walls as well. I read a post on another forum that said to leave either two windows cracks, or your vents open a bit. Since I have covers over my fantastic vents, I switched them to manual and opened them just a bit. I have had absolutely no issues with moisture since. We have been running the heater every day. Also, there has been no moisture issues when showering.

Life Well Below Zero: Let me say that I have camped in temps as low as -4F,  but just for one night and it got up into the teens at least during the day. The  only issue then was the water bay. The hydronic heating system (in my case a  Hurricane--which is the only heat in the water bay from the factory) is not  fully capable of heating that bay sufficiently much below single digits. More on  that later. I note it is very capable of heating the living area down below  zero.
 This was different. We had at least -15 at night and highs of 5 during the  day. This is so cold that a water hose outside will freeze solid within two  minutes or less. The bottom line is that I do not recommend camping in these  temps without modifications. Here is what I can report: With two electric  heaters and the floor heat (I was plugged in to 50 amp service) the upstairs was  70F and comfy. The hydronic heat exchangers cut in at times during the coldest  hours of the night. I would think as far as heating the living space is  concerned, you could go to about -25. The dual pane windows we have are a  joke in these temps: The bottom 1/3 of the metal frames were solid ice (inside  the Magna) as was the glass. The inside of the windshield was completely coated  with ice. The back walls of the cabinets mounted in the top of slideouts were  iced up on the inside. All of the foregoing was due to unavoidable condensation  from breathing, etc. I do not see how this interior condensation/icing can be  avoided given the insulation level of our coaches. I had an exhaust fan on to  the extent possible, but believe me, you are not going to crack a window at  -15.
 We had a bit of ice and snow. The Kwikee steps froze. Any ice on the steps  they won't operate. In fact, the step drive mechanism is now damaged and some  gear is partially stripped so they do not move in and out properly. I have to a  call Kwickee to discuss what needs to be replaced. The motor still works. If you  can live with the problems I have described, you would be OK.
 The limiting factor is the water bay: As I learned last year after a few  days in teen to -4 temps, the passive hydronic radiators CC installed to heat  our water bays are inadequate to prevent freezing much below single digits at  the most. In that earlier experience, I installed a 200 watt Lasko fan drive  personal heater in the front of the bay where the water pump and most of the  plumbing is and that (along with constantly running hydronic) was enough to keep  things from freezing. I did the same at -15 but after a day or two, something  froze preventing water from being pumped from the fresh water tank. It was not  the pump since the heater was literally a inch or two from it and my remote  thermometer near it read 47F even when -15 ambient. I assume some other water  line relating to the tank or the output from the pump froze since hooking up to  city water resulted in flow to all faucets and shower, etc.
 There is a fairly simple solution to this problem if one wanted to live  under these conditions (which I do not): Simply replacing the passive inline  water bay radiator (which has no fan) in the main water bay with a small fan  driven heat exchanger like those upstairs (lower BTU rating would be enough)  would heat that bay well into the minus F ambient numbers no problem with the  air circulation.
 Just for the hell of it, I started the Onan generator in -5. It was a very  rough start, but it started! The engine block heater was on so it started fine.  When I left in balmy single digit temps, I had no problem with any of the air or  hydraulic systems. The Hurricane running off engine heat (diesel burner off)  kept the interior roasty toasty as did the dash heat (with the "school bus"?  pumps disabled).

Good info sharing, Rich - you made me cold!!

We dry camped on Muncho Lake Strawberry Flats Provincial Park for 6 days on our way to alaska. The lake was still frozen over, and thick ice too. It was in the teens most nights. Our first major trip with the new battery bank and solar panels, so I spent some time testing them out. (X's 4 L16 Lifelines for 800AH. X's 5 240W 48V High Efficiency Sharp/Panasonic Solar Panels for 1200W, feeding thru the MidNite Classic 150 controller.)

I found that we could our stand alone portable electric heater on low during the day, and the solar panels would keep up with this draw. Day time temps would get up into the low 40's, with one day in the low 50's.

When the evening meals required the convection oven, we'd fire up the generator. I used that time to gain as much heat as possible. Would turn on the portable heater to high, floor heat to 90, and fire up the coach heating units (Our front register under the dash was out on this trip, so one in the front zone below the galley cabinets.) and have on the electric heat element in the Hydro Hot. (The 04 Allure has a single element, so it helps, but not as robust as the double element in other units.) A few nights while doing this, the diesel part of the Hydro Hot kicked in to support this heat running.

Once the generator was shut off, we'd just bundle up as needed, but frankly most nights the temp loss was so gradual, especially with the floor tile heated up, that we were fine until bedtime. Light sweatshirts for the wife, and I usually was fine in a thicker long sleeve shirt.

At night, we'd cocoon ourselves in the back bedroom area, with the door to front of the coach closed off, but we'd leave the bedroom doors open - as I seem to get up for night time activities much more then I used too:)! With a good blanket and comforter, and the extra body heat of our dog, we all were comfortable. Temps would drop down into the high 40's some nights in the rear of the coach. The front would see mid 30's.

I did leave the Hydro Hot Diesel on, and set the furnace temps to 35, but the furnace temps would not kick on overnight. The Hydro Hot would fire up off and on during the night, and that would protect the water bay for us.

I'd usually brave the cold of the front of the coach area around 5:00-5:30AM. Crack the window over the kitchen sink, and remove the kitchen roof vent insulation cushion (we have these in both vents, and they really help), and that vent was cracked about 3/4 of an inch. I'd then start our Heat Buddy (we took the big HB on this grip, instead of our smaller one), and set it to medium (Just one panel fired up.) and did not turn on the built in fan. I'd place the HB on the kitchen table (did this because we have the dog), and have it spliced in with a hose to a LP access that we had plumbed from the main LP tank to just below the fridge, beneath two drawers in our coach. We also had two six packs of the 1# bottles, as well as the 10# portable LP bottle I use with the BBQ and Campfire In A Can. So we always had plenty of LP available. With cooking via the stove top, LP fridge consumption, and the HB running - we were down just below a half a tank on the rig's main LP storage, after 6 days of dry camping, with about 4 days of non HB usage as we traveled to get to this campground.

The HB on medium setting, would get the temp up to mid 40's by the time I would get up at between 6:30-7:00AM. I'd crank the HB up to high, and turn on the HB fan. Fire up the inverter, make our pot of electric brewed coffee. Wait about 10 mins after that to let things 'rest' then check the SOC which was usually about 85%. (That includes a few movies at night, led lights, computers running, and Hydro Hot overnight.)

Usually about 30-45 mins after turning the HB up to high. I'd be in the low 60's. Would then turn off the HB. Close the window and put the insulation cushion back into the roof vent. Then turn on the furnace to 65 in both front and rear zone. The Hyrdo Hot would kick on as needed. This way by around 8:00-8:30AM, the DW and Dawg would feel it was 'acceptable' to come out of their beds and start the day!

With the longer daylight hours as we moved North, even at the lower angle of the sun, the SP would usually have us back up to full charge before noon, a few days with more clouds, it was 2:00PM before 100% SOC. But, we had also shifted back over to the electric heater on low setting, usually by around 9:30-10:00AM, and the outside sun was helping on heat gain by then too. It would not get dark until about 9:30PM - so the Solar Panels were putting out battery charging amps for quite a long day.

If we knew we were going to be cold camping in the low teens for extended periods, and be in the same place. We'd add skirting to the coach. We also would have put insulation into the skylight over the shower, our biggest area of heat loss. But, as I ran the Solar Panels straddling over the top of the skylight, I feel this has helped on heat loss, and for sure on heat gain in hotter areas.

If we were not dry camping, we'd run a humidifier, and get by without the HB without any problems down to the low teens for longer periods.

Best to all, have fun, stay safe,
