It will probably be in 2014. We began traveling full time in September of 2011 and will have covered all the states east of the Mississippi this year. Ours plans are to winter in the southwest and and visit the remainder of the lower 48 in 2013. We also plan a 2 month visit when we get to Alaska but we want to take time to enjoy Canada as well.
There is a lot of information available about Alaska on the internet and some of the more established RV forums have topics about it. It would be great if several of us could organize a caravan or rally to Alaska.
