Hilarious error in the 'trivia' section
Ironside's original truck was not an "armored truck" as stated in trivia here. Although a victim of an assassination attempt, even Ironside couldn't afford the fuel bill to drive an armored vehicle all over the place like he did. Plus there's no way he could get himself and a wheelchair through the rear hatch of a typical armored truck.
The correct answer is that his truck was a "paddy wagon". Basically a vehicle for transporting large numbers of prisoners from place to place - Still a bit of a gas pig. It was surprisingly old however, being a model from 1940 - you'd think he could have easily bought a 60's van as he later used.
