Hi Douglas, I drive this hi way about 30 years ago from California to anchorage and back. At the time it was mostly gravel past the Canadian border. I hear they have paved allot of it now. The gravel was hell on tires and the road was rough as hell. Windshield took a beating from rocks kicked up by on coming trucks but not as bad as it could have been because of advice given to me by a friend that familiar with the road. He said when a truck is coming at you too get as close as possible when passing because the rocks that are pinched out from under the trucks tires are coming up at an angle from the ground. If you are close the the rocks are at wheel hight but if you get over more to the right the rocks are higher off the ground at windshield hight. When the other guys say get fuel at every chance they aren't kidding, it's a long way between stations. I would carry a one gallon gas can with you. Also a tire kit as posted earlier is a must because you are on your own out there. We would drive all day with out setting another soul some days. You have cast wheels so you can use a motorcycle tire plug kit, it's similar to an auto tire plug and it works because you don't have inner tubes. Some kits have little CO2 bottles with a fitting to air up the tire but I would also carry a compressor. You'll need to wire in a plug from your battery to power it. The tire concern is paramount and you need to be able to get yourself going again if you get a flat.I got a flat from a sharp rock. I'm sure cell phone coverage is limited out there and you couldn't even call for wrecker to come get you and your bike. I don't mean to go on about this but if you got a flat an hour before dark and it took 6 hours for a wrecker to get to you, if you could get a hold of one, let me tell you there's a lot of wild life out there especially after dark. It was a trip of a life time and I want to ride it some day but one must be prepared because as I said, you are on your own out there
