13. 1965- 1971 International Harvester Scout 800
The International Harvester Scout 800 is one of the most popular collector trucks around, and with good reason. The original Scout quickly gained a loyal following and a lot of attention for its superb off-road capabilities. In its heyday, it was arguably the best truck of its class. The original 800 was barebones and lacked many creature comforts but the 800A and later 800B would add many then-modern amenities. During the 1960s, International Harvester Scout even managed to outsell Jeep, making it the most popular 4X4 of the time.
