I have made the trip to SE Alaska (Haines) numerous times since 2004 and always solo since my wife doesn't like the idea of the long drive from Colorado. I'm 77. In 2014 I started out and made it to MT before turning back due to illness. Turns out I had stage 4 colon cancer. It's in remission now and I'm heading off again in early June. It just takes a little planning and a certain mindset for being along a lot. Satellite radio really helps too! My only mechanical problems occurred in MT. Otherwise, it's just a matter of plodding along enjoying the scenery and wildlife. You're lucky to have the companionship of a dog. Our old cat wouldn't enjoy it and wouldn't talk to me if I took him. :-)
