If you have been out west in your MH you will be right at home in Canada and Alaska. As far as roads I have been on the same thing state side but you will see much more in the way of frost heaves, biut most will be marked with a flag a cone or you will see a wiggly stripe for a centerline or fog line. You will quickly learn slow is better and find as we have friends along the way. With a tour you will be on their time not yours. Get on a couple of the Alaska blogs and get two or three books and a good GPS, although it's hard to get lost, not that many choices for roads. I would carry a spare either mounted or just the spare tire. RELAX AND HAVE FUN!
