We have a lot of major issues covered on hundreds of threads here. What about the minor, smaller issues? Add what you know.
First - You will be wanting a block heater on your vehicle engine. That has been discussed in detail here. You will need an extension cord that is cold rated to power that block heater. While you are at the store, buy two cords. Why? Because when you are new to the idea of plugging in your car every day you will come home one day and see that someone has stolen your cord! Actually nobody stole your cord. You forgot to unplug it and drove off that morning with it dragging on the ground to eventually be yanked off when you turned a corner and drove over it. Sometimes the cord will be sitting in your driveway, or just down the street. Other times it is lost to the snow banks of time.
I bring this up because over the last week I have seen three brand new cords hanging out in the middle of various streets across town. When you see a beat up, electical tape spliced cord without original plug ends on it is when you know one of us old timers was in too much of a hurry to leave home that morning.
You will also be wanting a good outdoor timer for the block heater.
Second - Everybody is concerned about freezing to death up here. Yes the Arctic and Sub Arctic are cold places to live, but you won't be living in a tent the whole time so the cold is not going to kill you as soon as you step outside the house. The real issue you will have to adapt to is the midnight sun. Its June and the sun is shining in the morning and the evening, and at night time. What? It is much harder for a number of folks to adapt to the summer daylight hours than it is to adapt to the cold. The winter darkness is another issue on its own. Both problems can be handled over time, but the first summer could suck much worse than the first winter. Start taking your vitamin D now. Everyone north of Seattle should be dosing daily.
Third - Alaska is the largest state in the Union. It has fewer miles of roads, paved other otherwise, than a small east coast state. We might have more miles of road than Rhode Island, but I doubt it. Alaska does not have the agriculture and forestry history that created the demand for the majority of roads in the States. We also do not have the population to drive the need to be connected. Small planes serve the state transporation needs. Some folks still want a road to Nome, though. So, you can't drive all over the place like you can in the States. You can still take some epic road trips though. You'll just be repeating them every few years.
Fourth - If you have a dog, come spring you will be cleaning up an amazing amount of dooty from the yard as it melts out of the snow. No matter how much you scoop up during the winter you will still miss a lot of it. When it snows a few inches every week you kind of forget about getting out there on dooty duty and come spring its just a mess. And your dog is running through it and then coming inside and walking all over your house with that "mud" on its feet.
