There are enough truck owners to warrant it. The market for trucks/SUVs in Texas is HUGE (anyone have stats to back me up? I know I've seen them before)... that's why GM has a plant in Ft. Worth, Toyota is building the Tundra in SA, every manufacturer has a Texas Edition truck, the commercials for trucks here are texas-specific, etc.
I can't explain florida though.. Maybe the cadillac forumn justifies it with all those old folks
