My Brother Feeds Zombies 7:

It really did not cost that much extra or add much weight to the truck.  The steel skid plates add the weight, but we had the power to handle it.  I felt like MadMax looking at the first production truck out of the garage.  It was awesome.  We put full blown cattle sweepers on the front, like an old fashioned train.  The angle was designed to keep objects away from the run-flat tires with bead lockers.  They were modified run-flats.  I had them filled completely with a soft rubber compound.  They could be fully shot through and still roll 10,000 miles without needing to be changed.  You just can’t pull over and change a tire in the wild and I was pretty sure things could get pretty wild, real quick.
All of the fuel tanks were reinforced and divided into individual fuel cells.  If something did get through the armor, it would not cause more than a few ounces of fuel to leak out.  We could not stop and did not want to add any fuel to a fire, if one broke out.  Of course the security was extreme.  This was actually more cost effective that I through it would be.  Sure setting up all the arms and equipment cost quite a bit, but because it was so intimidating, no one would even give us a second thought.  There were easier ways to die than to mess with one of my convoys.
