>>1408708>how do I not get stranded and die?The same way you manage to not get stranded and die during any other long-distance drive.
1. Have a vehicle in decent repair that doesn't have a history of shitting out on you
2. Keep spare fluids (brake fluid, oil, ATF if you drive an automatic, distilled water/antifreeze) in the vehicle
3. Make sure your spare is in good shape and accessible, and that you have the tools and ability to change it
>found out the hard way last week that the last time I had my tires rotated the retard with the impact wrench rounded off all my lugnuts by using the wrong size, so I couldn't actually get them off with a lug wrench and had to hammer on a too-small socket and use my own impact wrench to get them off, trashing the socket in the process4. Keep at least some food and water, and cold weather clothing and a blanket in the vehicle
5. Wear weather-appropriate clothing during the drive, don't rely on your car's heater/AC to keep you comfy--if you have to be out of it for long periods of time to fix something you'll suffer
The entirety of the road including the "optional" section is just a hair over 400 miles. While it's unpaved, the majority of it is graded and kept in good repair, enabling most vehicles to be able to traverse it at almost-highway speeds. It should, in good weather, be a single day's trip.
