I'd buy a surplus military generator before I would invest in an EMP shield. Most likely the whole power grid would be severely damaged. A CUCV truck would be really handy if it is the service edition that runs a generator off a PTO. Older diesel trucks more likely to survive than newer vehicles that rely on semiconductor components to run. Links below show some options.
