The International vehicle was called a "Travel-all", and was similar to the Chevrolet vehicle, a station wagon with the same front end as the pickup. The Boy Scout camp I attended back in the 60's had a mid-50's, military-surplus Suburban called a "Carryall" by the camp cadre, so it might have been a military term for the Burb. That's not the only place I've heard the name, though.
