Making it thru the cold for the first time - doing well :)

We saw -8℉ this morning here in upstate NY, and the two coach furnaces kept us warm and toasty. Since we're parked next to our vacation cottage, we're running from the 320 gallon bulk propane tank that feeds the cottage furnace, so the full onboard 24 gallon (100 lb) tank hasn't been touched. We'll be switching to that when we head south next Sunday though. We really would have preferred to be there by now for the weather, but spending the holidays with our kids, grandkids, and great grandkids is more than worth the discomfort when we step out the door.

Sounds like you're doing well with the cold. I've never actually camped in the extreme cold (below freezing) for more than a day or so, but we use the RV as a guest house so sometimes the kids will stay out there when it's very cold. The 2 propane furnaces do quite well, but the ducts are not in the floor. The Pergo gets crrrraazzzy cold - that was the only advantage the carpet had over the laminate floor.

The furnaces really suck down the propane so I run the electric heater anyway, even though the furnaces keep up just fine. I don't have any scientific measurements but it has to help reduce propane consumption at least a little.

For truly cold weather when using electric heaters, consider replacing the return air grill for the furnace with twin window fans:

We've been to -5 in our coach. We use the electric heaters for most of our daily heat and also use a low voltage electric blanket at night. For us an interior temp in the 60's is comfortable.
We love the fact that most of the National Parks are almost deserted during the Winter and this gives us a chance to view the wild life and natural beauty at our pace without worrying about any crowds.

Interesting report. You sound well prepared.

We really are doing great and I wasn't sure what to expect.

It's 16 degrees this morning and the furnace has been set at 64 and cuts off when it warms up. :). Furnace doesn't stay off long, seeing ~9-10min cycles off, & 4 min on. We had it on 68, but that was to warm for us. should have known since 62 is what we sleep in back home. Haha

I had engineered hardwood floors installed ~ 1 1/2 years ago and they stay pretty warm as well. Ducting is in the floor. I did bring 2 sleeping bags and used them to fill the gap under the large slide in the living room and appear to have no draft from under the slide. We have a few rugs, but again, the floor is not really cold. Coldest place seems to be back of RV passenger side floor where our small slide is, buts it's not freezing, just colder then most and I notice it since that's my side and where I place my bare feet in the morning getting up. :). Still not bad though.

Overall, I'm very happy with how the RV is handling the cold. We've already been through a low of 15, high of 28 last Thursday and I'm not concerned about the next 3-4 days of highs in the 20's & lows ~10. Got plenty of propane to make it until we head out Wednesday as I topped off last Friday heading into the long weekend.

Stay warm and Happy New Year!!

Good to hear a positive report.
Seems like when it's really cold outside, you can heat the RV but the floor is super cold while the ceiling is toasty. Sounds like your doing OK though!

Glad to hear a positive report on the "cold" ... Many other folks seem in quite a panic about it.
