I use mine more in the winter than summer, in very cold temperatures (below 0 many times).
I would definitely recommend a Genturi for your generator exhaust, if you get wind from wrong direction or snow you could be exposing yourself to Carbon Monoxide.
Make sure you use your ceiling vent for showering, cooking etc. The extra moisture is important to get out of the interior.
If you are running your generator, I would consider extra space heater for your comfort, but may not be required.
I prefer a heated mattress pad instead of the heated blanket, but that is a personal preference.
I would also purchase a wireless thermometer for your basement so you can monitor the temperature in the basement, especially utility compartment. I would place a space heater in utility compartment as a backup just in case, I have found 100 watt bulb isn't sufficient on some nights with the wind/cold. I also lay an old blanket on the plastic bottom which has drain holes in it for extra insulation.
Leave your glow plug plugged in the night before you leave and make sure you have filled with winter blend diesel or appropriate additive.
I have never had any problems other than a black valve freezing shut once, since I keep the space heater in case I need to thaw things out.
I built my own heated hose, very easy, but you won't need that based on no utilities available.
I put out my slides, heat was already on, if I'm running generator or have electricity the heated tile floors is on, and enjoy.
I have spent many days in below 0 weather, in CO, SD, KS, and MO, I think you will be surprised how easy it is, especially if you don't have water/sewer hoses laying on the ground. Good luck!
