Hey, as you are already aware , U.P. winters, can be interesting....to say the least...........
I live in T.C., so , I am a bit warmer than you. First, formost .......how are you going to heat the rig?????? If you are going to use propane, you need a
MINIMUM 100 lb tank,( or larger) the big one ..................your heater will gobble up propane .trust me on this one ............
...Is it going to be in L'Anse area???? Sounds like maybe back yard??????
You need to deciede if slides open or closed....duhh, if living in , will need to be open
..which means ....you will HAVE to leave them open all winter, ice, snow will build up, and you wont be able to close, open , let alone seals freezing,
if you put in, snow will melt in warm rig, run down inside........
....and more propane, slides not nearly as well insulated as rest of rig (top, bottom of slides, any slide , not insulated well at all.)
So, plan on clearing snow off , oh every few hrs , from the slides
,(the weight will be a huge factor) the way it snows up there..
...Hey, are you still interested in doing this ......
OK, we continue.if only on weekends, then heat all winter...???, if not , heating, cooling, heating, cooling ....people inside, is going to generate a lot of condensation ....read moisture every where...
Water system, Oh....dont forget ...........................
THE FRIDGE will not work , unless you heat the outside part, where coils , etc are....once again, trust me on this one .....I cannot use my freezer, ( below about 30 degrees outside), it will not cool, because it thinks it is cool, just heating inside of rig , will not work.
I have lived through all this , this is how I know this ............
.........
Water system, you will need heated water line, and unhook hose between tank fills...otherwise hose will burst on some really cold night .....once again, dont ask me how I know, been there, done it, got the shirt....
. I believe you WILL NOT be able to leave hooked up all winter, and use hose as in summer.
Wow, toilet, shower.......hope you have tank heaters.......but, where , how are you going to dump.????
...frozen Black water .....not good ............
If you use elec heaters, the basement wont get furnace heat, and you will freeze water lines....which in the U.P., you prob will anyway Wow, frozen inside lines cant even think about it ...
So, I Feel , you can get away if you USE NO WATER , and use a cooler , ( inside house freezer for frozen stuff.) Once again, I tried to use my rig one winter as extra space , did not work. These rigs are Just Not Built for year round, four season use in Really cold climates...
I hope I am wrong, but ,,,,, I think you will just be able to use it as a space ...for Hanging out in , not really use as a cottage , in the DEAD of a U.P. winter.
So, if any more questions....fire away............................
.(sorry to be a realist about this )
But once again, just my views, having tryed what you are proposing....
