The light line of trucks was marked by a larger range of transmission and wheelbase options than any of its competitors, and in general the lineup aimed to maximize adaptability.

[3] Production ended in late April 1975, as a hard-pressed International chose to focus on the Scout and on heavier machinery.

Sold as the 1000 through 1500 D-series, the Light Line pickup was originally offered with four of International Harvester's own V8s, with displacements of 266, 304, 345 or 392 cubic inches.

Several models were also available as a cab on a bare frame for construction of stake-bed or other applications, some with an optional dual-wheel rear end, with available load ratings up to seven tons.

[2] From that year on a metal grille with five horizontal bars and a slim central vertical opening was installed instead of the previous plastic unit.

[3] The 1010 and 1110 have the same weight rating, the difference being in the front suspension: independent, by torsion-bars, for the 1010, and of a solid I-beam construction for the 1110 (and all heavier versions).

[13] The oil crisis particularly affected International's working trucks, which were the heaviest and least fuel efficient in the market.

Another issue of concern was the truck-centered nature of International's dealers, while most competing light trucks were beginning to be sold to suburban buyers in more alluring and better located auto show rooms.

[11] International Harvester instead chose to focus on heavier trucks and the popular Scout, which continued to be built until 1980.
