Finally after a long search I know what the screw jack on the right rear of my truck was used for. The truck came from the Army Missile Command in Europe it's a V-126 radar truck. The jack leveled the truck when the radar was in use to identify the IFF signals of aircraft to decode friend or foe![Very Happy :-D :-D](https://www.steelsoldiers.com/images/smilies/icon_biggrin.gif)
