Gas stations occasionally run out of fuel in Yukon. Not an issue in most communities as there might be another station but if you're counting on fuel in Ross River or Pelly it can be an issue.
One stop at Pelly the only station was out of diesel and they didn't know when the truck was next going to deliver. We had enough to make it to Carmacks to fill there. However, RVs were parked in the campground waiting for fuel delivery. Five gallons wouldn't have helped though, the next available fuel was quite a distance away.
