A year ago we didn't hesitate to go anywhere up north (Yukon, NWT, Alaska) with an extra 5L can of gas. Never passed a gas pump without topping up so didn't need our 'reserve' gas but had it just in case. Some riders carried more than 5L depending on where they were headed, the weather forecast and in case a road was closed and they had to turn back before the next gas. There's a lot of little mom and pop pumps and card locks on the longer stretches so we won't know for a while if or how Covid affected these. If anyone is headed up that way next season I'd suggest ordering a copy of the 2021 Milepost to familiarize yourself with that and also post any questions on the Alaska regional forum on advrider.com as they'll have current info before the next riding season starts. I think the Trans Tiaga would be a great ride but more of a logistical challenge WRT gas and I don't know where or how to get info on that. Also I'm assuming that's a mostly camping trip so there's extra weight and wind resistance on your gas mileage. Maybe someone on here has ridden the Trans Tiaga or plans to and can chime in?
