Agree with AKsilvereagle. There are plenty of hares on the AK highway. We are very much one of the tortosis. For us the Tok to Haines Jct leg takes 2 days with an overnight at Snag Jct Provincial Park. Always amazed at how many times the same vehicles overtake us during the same day. We stop occasionally for potti breaks which always include a visual check of tires & running gear.
Driving at 45, slowing down to whatever is necessary, when necessary sure beats being broken down on the side of the road doing 0mph wondering how to get help.
