Gentlemen;
A "war" is not needed at all.
I've always felt that by doing it this way (Chevy & GMC trucks) it gave them, (GM) a larger 'market share' by having two truck divisions, having several models each.
Remember; each of the competition had only one, back then.
This of course, was long before the Falcon Ranchero was copied and allowed to flood the marketplace.
The rest is history, I guess.
