A few years back I saw what had to be the most INSANE Ferrier rams EVR up at Massdiesels. Full body like a Roach coach (cater wagon) that had his compressor , welder , and a SERIOUS inverter in the center portion completely out of sight. the sides and rear opened to reveal 20 or so basic shoe sizes all neatly laid out , a press, vise , and jig all slid out on a bench , all the doors when open made a canopy like setting with full 110V flourescent lighting , the works! Even had a quenching basin. Absolutly an awesome display of a very well planned out rig ... . With "Ahem" HORSEPOWER as well... . pretty bombed up if I remember. All things loose had a retension system to it. shoes , wrenches , hammers , awls , punches ... . everything stays in place no matter what the conditions are whilst driving.
