As is the case for automobiles, the potential EMP vulnerability of trucks...
Five of the 18 trucks tested did not exhibit any anomalous response up to field strengths of approximately 50 kV/m.
Based on these test results, we expect few truck effects at EMP field levels below
approximately 12 kV/m. At higher field levels, 70 percent or more of the trucks on the
road will manifest some anomalous response following EMP exposure.
Note that the vehicles were only tested up to a MAXIMUM EMP field strength of 50kv/m (that 50,000 volts per meter). The problem is, if there is a high altitude EMP attack, and a "Super EMP" weapon is used (Russia and China admit that they have these, and supposedly the DPRK - and therefore by collaboration Iran - may also have these), vehicles may be subjected to upwards of 200,000 or 300,000 volts per meter! No vehicles in the USA have been tested at field strengths that high as far as I am aware. Anything above 50kv/m is unkown (but results are not likely to get any better!).
For my money, an old Army truck, the M35A2, is the best "bang for the buck" BOV. As close to EMP proof as you can get and they are cheap (that's why I bought one!).
