While I would only loosely call a Scout a Truck, it needs to show up here somewhere. It was the International Harvester solution to a Jeep. They were getting to be fairly popular in the early 1970's when the gas lines appeared. These things were heavy and featured the same engines as the intermediate (LoadStar) series IH trucks. They just chugged from gas line to gas line. IH wrote off their whole light lines beginning at the end of the 1975 model year. They made some Scouts for a few years after that, but the larger Travelall and the pickup line went away. The cost of redesign was just too much. They had been making them by sharing a lot of parts with the larger trucks, but the push for fuel economy was going to require more careful designing so they flicked the whole product line.
The Scout continues on, but it is an orphan. They really don't make them like this any more, but they have quite a following.
