The subject of EMP proof vehicles has been on my mind for the last few days. My father who is in his nineties has had to quite driving and he gave my wife his old pickup. She has always loved that truck and he kept it in good shape.
Since it is a 1972 Chevy that he has owned since it was almost new, we knew the history of the truck. In the 1970’s when President Carter was messing up the economy and the gas crisis occurred he had the truck converted into a duel fuel vehicle. It burns both propane and gasoline and has two gas tanks and the propane tank.
It still has points instead of an electronic ignition system and would probably survive a EMP attack. Our other vehicles are newer. So we had our mechanic check it out and he said everything seems fine and it is in good mechanical condition.
Well the other day despite the drought we get a lot of rain and the ground became quite slick with mud. My wife decides to take the truck for a drive. The truck in under a shelter and as soon as she gets out from under it the wheels start spinning. She can’t get up a minor grade to get out to the pavement.
So I go and look at the tires and find that while the tread looks good at first glance, they are street tires and look quite old. Getting down in the mud I look at the date located on the side of the tire right by where it says DOT. The tires are from 1987. First failure, I had never taken a good look at the tires, time to get new mud and snows.
Second, I realize this is the only two-wheeled drive vehicle that we own. So I called one of my sons, who is an expert in off road driving. He has competed in major rock crawling completions. He suggests that in addition to the new tires that I have a locker (http://en.wikipedia.org/wiki/Locking_differential) installed in the rear end. This will keep just one tire from spinning and make the truck more functional off road.
Now this is a good example, when the truck first arrived I would have trusted it to do what I wanted, and planned on using it in case our other vehicls went down from an EMP attack.. But when we took it out in the wrong conditions Murphy’s Law struck and we had a failure and couldn’t even get out of the yard. But a new set of tires and a locker and all will be fixed and we will have a truck that will function after an EMP attack
This is a good example of why we always need to practice under adverse conditions and not just when the weather is nice.
