Did you ever mistake a Chevy pick up for GMC? No wonder as those have been virtually identical apart from the grill and logo since the 20's.
The difference is Chevrolet trucks were marketed towards private users, while GMC was intended for commercial use, so it's more about market segmentation than anything else.
