Longest I have stored my car is a year so it sat covered in my garage. long term I cant give you a lot of advice.
However, when you get to alaska NEVER, EVER say you "don't normally travel back to the states on my vacation time" or anything close to it. Alaskans like Hawaiians do not take kindly to someone that gives the impression they don't consider them "in the states". Refer to them as the lower 48 if you want to make a distinction LOL! if you go to hawaii refer to "the contenental 48" or something along those lines.
