Plumbers, please do sell your used service trucks to Jihadists. Just leave a few “pipe” bombs hidden on board, with a GPS/audio safety mechanism so that they will only explode in a specific region, after the sound of gunfire and shouts of “Alahu Akbar!”

If they did that Ford could never sell another used truck in their corporate headquarters- Dearborn, Michigan. Used trucks would be blowing up left and right.
