I might be able to help more if i knew some things. maybe these would be to personal, I don't know.
One might be Year make and model of the car/van/ truck?
4x4 can be good, ftwd is ok. A good battery is key..... In winter run the car on the lowest octane you can with NO Ping.. In winter time you want unstable fuel to explode on cold mornings, and to get the best bang for the buck.
Many days in jan and feb will not get much about the low teens at noon... Nights will tend to be well below 0.
It's colder there than it is in Tamworth with many cold and snow bands between.
Your dog might need boots serious... You will probably find the dog won't much care for boots too, and in that case if he acts like he has stepped on a thorn it will be a ice ball gagged up in the foot that he limps on.
You both will need to drink more water.
Add cookies to the car kit or something else high in carbs for just in case.
There will be places a cell phone might not work.... not sure where in around Littleton but up on the kanc there is a slew of dead ends to phones..
Lots of people are telling you it isn't that cold in NH, I beg to differ and i bet they live south of Concord.
Buy and use driving gloves.... Wet hands on metal in dead winter will remove skin....
I am going to look pretty stupid if we have a winter like the last one was, but i don't think it will be like the last one was.
I think this one will be 13 decent storms and colder. Just a hunch.
What the place is like might help too......
What kind of heat it has, and who pays for it, How old the building is too lends ideas......
I hope it isn't pre 1900 and or brick...
If you ever want to let me know and come to N Conway I will buy you a beer or a coffee...
I could show you around down here a little bit. Only in summer do I get to the Littleton area on the bike anymore.
Once I had friends there, running a store that sold Native American items, but the guy passed on and am not sure where his wife went.
I never really shopped in that area, I know there is town and just Nor-west is a walmart, but walmart won't have any good winter clothes period....
Don't buy cotton long johns, and other cotton killer wear for living up there...... if you can stand poly pro on your skin buy that, if not buy cotton wool two layer duofold longies.
Labonville will have good woolens and loggers clothing which is ok but can be heavy. I wear the jack shirts all winter as a coat but i like the real cold and know how to dress in layers.
You will find out!
I am the old guy
The kid was the RMC Gray Knob caretaker that year...... I was once one too as a sub....
RMC does the northern presies, of which you will soon be seeing to your east by south east
May as well have the other one too...
Summit of Jefferson dusting my brother's ashes to the 4 winds....Another part of life.
Oh the mt line in the far distance is where i live, just over the to the south side.
