Sorry to hi-jack this thread, I just watched the short, way too short video clip of the 1932 RTW adventure and need to see all of the adventure films offered on that site....what a treat those films would be. Damn!
Back to topic.....I also have thought about a RTW trip almost in the same route you are taking without the USa portion and staying within Canada.....but soon stopped the thoughts when I found out the costs of getting from Vanvouver to the far east. Have you priced this out yet and what did you find? I was so shocked it finished my RTW adventure before even getting off the ground.....sadly.
Fuel will be a huge issue for such a short range machine, I get double what you are talking about and still think it not enough carrying 5 gallons extra.
I'm in for sure.......good luck and I'm all ears!!!!
