This is what our "winter cottage" looked like back in September--almost three months ago--when we were just starting to plan for our travel adventure. Winter seemed a long way away at that time.
We knew little about RV'ing and little about what we would need to live away from our normal environment. 
Since then, we have learned some things about both.
I can now take the camper off the truck and to load it on. Each time gets a bit easier for me, but B still can not watch the process. During the three months, I have kept the camper connected to the shop's electricity in order to keep its two batteries charged and allows electrical appliances to be used inside the camper. I have also kept the heater on, set to the minimum temperature setting. This has kept the camper at 44°. The heater runs on propane--the camper has two twenty-pound tanks. With the cooler temperatures that we have had the past few weeks, a tank last about ten days. Surprisingly, that temperature is comfortable when we have to be inside. I did learn that in extremely cold temps, the propane flow may be a bit erratic. If the flow to the heater stops, I learned that the thermostat has to be reset in order for the heater to restart. This bit of information was learned during a call to the dealer.
B feels comfortable about cooking in the camper. She has purchased cooking utensils that will be used exclusively in the camper. She has also planned out where everything will be kept and what type of meals she can cook. So, we should be in good shape and, hopefully, not too much out of it when we return. 
Right now, the camper is on the truck, and loaded with just about everything we will need when we leave in a few days. It is also loaded with some snow--and more is expected tomorrow. Maybe this is nature's way of wishing us "Bon Voyage."
Our decision to travel into some of the southern states for two months has made it necessary for us to arrange for a mail delivery service. The US Postal Service will only hold mail for a maximum of 30 days. We have signed up with a company in Florida that provides a temporary mailing address where our mail will be forwarded. The company will keep us informed of what they have received; then we can have them send the mail to us by FedEx when we are ready to receive it and staying somewhere for a few days.
We have also gotten into some technology as a result of this trip. We now have a wireless phone service; we each have a cellphone and a device that gives us a WiFi internet connection where and when we need it and inside the camper. This frees us from having to rely on public, unsecured WiFi.
In addition, we have added a VPN (Virtual Private Network) software and service to our computer.  This removes our identification and encrypts data sent from our computer, relays the data to its destination, unencrypted, then returns any reply to our computer encrypted, where it will be unencrypted. This is all to hopefully prevent identity thieves from intercepting any of our personal information that we need to send out during our trip. What a wonderful world we live in!

Today the "winter cottage" looks like one. Winter has not officially arrived, but it sure looks like it. There was twelve inches of snow last night. Nice joke, Mother Nature! I got the snowblower out to clear the walkway and driveway so we can leave on Tuesday. I also had to do the thing that B doesn't like me doing: clearing snow off the roof--this time, however, it was the roof on the camper.
