A couple of things you didnít address

Did the truck die 100%? Most times with a blown head gasket it still runs, it just gets hot quick and runs out of water quick. Both could be addressed with some extra water and driving the truck for only 5-min at a time and letting it cool down and refilling the radiator (leaving the cap loose prevents pressure build up) and driving for another 5-min. In 5-min of driving you could easily cover 3 or 4-miles or so.

Why did you not sleep in the cab of the truck, itís insulated, water proof and wind proof? It would seem to be better then makeshift shelter and itís already made.

If itís only a 40 acre farm, why not walk the 40 acres to the house?

You can run, but you'll only die tired.
