One relocation venue that may be worthwhile is some form of mobile home with which one takes an "early holiday" to a safer area when the cataclysm draws close, leaving for the holiday about a week ahead of things starting to happen. People that cant find themselves able to justify the financial outlay of a ready-made mobile-home can buy a used lorry or military surplus truck and do some cheap modifications to allow it to function as a mobile home. I myself am planning to rebuild a US M46 type military ehicle for this purpose. A budget of ca. $3000 for the vehicle and $1 to $2000 for the modifications is a realistic estimate, at least where I live (Scandinavia). The "slightly above average" do-it-yourselfer can, with the budget above, create a mobile-home that will rival all but the most expensive of mobile homes. Also, a vehicle that can tow some form of trailer behind it will allow you extra space for needed supplies (seeds, fuel, water filters-tools etc.)

A prime reason for having a good set of mechanics tools and a couple of general car repair manuals. One may also want to include a small sledge hammer, wrecking bar or similar in the car to enable the easy removal of the front or rear window glass which can be very stubborn. Scavenging will be the major source of mechanical supplies post pole shift.

Dont forget the generator can be used as a wind or water driven battery charger, a bank of car batteries or even better deep cycle batteries from caravans and mobile homes will give a lot of useful energy, the rest of your car is so full of useful stuff to aid survival, there wont be a shortage of wrecked cars to scavenge from.
