I'd look at Arctic Fox brand, they are heavily winterized. However lots of windows probably does not fit well with winter in Alaska. You might want to ask this over in the Alaska-Canada forum here, they may have some ideas. You would certainly want to install skirting around the bottom of the RV and add heat tape and maybe insulation under it. You have to worry about propane bottles getting too cold as well as the water connections freezing.
How many hours of light does Homer get in winter? Not many is my guess. I see the sun rises around 10 AM and sets at 5 PM and the average high is 29 deg with a low of 19 (This for mid January)
