While you could make a small block chevy powered truck pretty bad ass, it will never be of the offroad capability of something like a unimog. Plus the fact that you may have to run a road block or something ....
Do not underestimate the effects of EMP. "Sunspots", a form of EMP have crushed powergrids from time to time, and have affected vehicles as well. One of the lesser documented damages to the U.S Navy Fleet that observed Nuclear tests in the South Pacific was the failure of some of the electrical systems above the hull line. For some ships, Carriers, and non-armored vessels the damage was so severe that some had to be taken in tow.
EMP is the most frightening form of attack that we face. It only takes one or two properly tuned devices, detonated at the right place, and the right time, and the correct altitude to destroy our lives. This danger is not overstated, it is vastly understated.
