I was reading the Profile on Dr. November  and you are right–lots of great preparation! One item though, at least from my perspective, seems to be in short supply. That is the amount of diesel fuel he has on hand for his equipment and generator. It would appear to be out of line with the rest of his stocks.
Of course we don’t know how much solar power he is able to produce, and how much he needs to run his genny, but if he lived in gloomy Ohio he would not have enough diesel on hand to go along with his six years worth of food.
I believe he should at least calculate how much diesel fuel he uses when he is off grid. We have a new 10 KW  Kubota and use about 3 gallons of diesel a day. His tank would last us a little over two months.
Of course everyone’s circumstances are different but it would appear that the Doctor should look into burying a large underground tank for his needs. Off road diesel fuel [un-taxed home heating oil] with the proper additives will easily store 7-to-10 years in an underground tank. If the fuel begins to show signs of aging and has not been used he can then have his fuel supplier pump out the old and replace it with fresh.
Lastly in the event that he can no longer obtain On Road fuel [taxed diesel] for his equipment and trucks he could use the diesel in the underground tanks for those needs.
In regards to the rest of his preparations, repeat after me: Thou shalt not covet thy neighbor’s house,Thou shalt not covet thy neighbor’s house, Thou shalt not covet thy neighbor’s house. 🙂
