Not sure how detailed you guys got with your fuel planning, but I made an Excel file to plan for how much I'll need. The mileages on the upper left corner don't mean too much, as they were just for me to approximate the time needed for the trip. Camp spots were just arbitrarily chosen mileages. The distances between gas stops are approximated, but within 5-10 miles of actual distance. My route is going to be Northeast PA to Matagami up James Bay Rd to Radisson to James Bay to Radisson To Trans Taiga Rd to James Bay Rd to North Rd to Chibougamau to Northeast PA... Just to give you an idea of how I figured mileages and whatnot. Hope this can be of use to yas.
