We have completed a 3+ month trip to Alaska in our 2009 Montana 3000RK. Although it wasn't without incident, we came back in one piece (with a few new screws and some duct tape holding things together) and it was truly the trip of a lifetime. We drove there in 2004 and this trip was even better than the first time.
Carol blogged every day about our trip, both the high points and the low points, so if such a trip might be on your horizon, you might want to check it out. The trip began May 17. Go to
