OK, I'm officially envious, (LOL). We are in the early planning stages of an expedition like yours up through the Canadian Rockies, then through the Yukon, across the Denali highway, then north to the Arctic Circle. If it all comes together it'll happen in 2019. What would be your very best advice for a guy like me, ( very experienced in the lower 48 backcountry ) but a novice to all things in the great northern wilderness. Obviously fuel range being of primary concern... For us it would be quite a trip as we would have to cross the continent. Thanks,
