All of you are welcome. Experience is that things don't always go well, so, while being prepared for a breakdown seems common sense, it is, for example, the confidence of being out and moving around in the rain while staying dry that relegates the story to past experience far sooner than when one is soaked. Being alone only heightens this.
Driving is a physical feat strongly affected by morale. Truck drivers speak of the phenomenon where the truck slows to cover nearly no miles at all over a given day; not explained by usual restraints. It's emotional & spiritual.
Glass prep via BB (who've mastered the chemical composition of the water/fluids applied) and use of RainX plus dedicated cleaners is strongly indicated for driving west as it means driving into the sun as the day progresses. Road film hazes perception of smaller objects at a distance. Why side mirrors and side glass matter more than windshield.
Also as to vision, DOT requires CDL drivers to have at least two pairs prescription eyeglasses. And I'm very happy to recommend www.DRIVEWEARlens.com
If it hasn't been mentioned here, then USDOT has a page on its website listing State links for road closures and construction. These may not be perfectly up to date, but should be a good way to eliminate some routes if needed. The concern should be more WHAT route is being used for a detour.
My son and ex weren't as enamored with road trips as I. I learned to spend my trip planning time combining the mid day break with locating the fuel stop and use of the Sterns' website, www.roadfood.com
to please us all. That, rather than the nights lodging, became the focus of the day. Believe me that truck drivers do much the same even if the choice is Subway versus McDonalds.
Finally, truck drivers are limited to no more than 70-hours or eight days without a break. Even though this proposed routing calls for short mile days, it is more challenging on a mile by mile basis. Thus I'd like to recommend as Plan B the following:
Once at about the 98th Parallel (fifty miles west of IH35; a line from Dallas to Minneapolis), population density all but disappears until one is on the other side of the Sierras. Driving becomes easier.
But the need for extended rest has grown. Travel takes "it" out of us. Thus, a day off the road to do a few chores, but mainly nap on and off all day is what many CDL drivers do during their 34-hr "restart ".
The Rockies, the Intermountain West and then the steep California mountains are a challenge of their own. It's a literal different country than east of The River. Prior to the Interstates, it was not so easily traversed.
I don't have to be in the mountains to enjoy them. Just have them in view. Thus I'd choose based on traveler amenities, not just campground scenic qualities for a restart. I already know I can likely increase my daily average miles on total energy expenditure basis once out West.
Look forward to pics and commentary, OP, should you choose to share any.
