That's because Texas is the largest truck sales. Its basically makers pandering to Texas knowing that if they put "Texas" on it Texans will buy it up just because it says "texas" and it must be better.Do they have Florida edition for their trucks? Here everybody has a "Texas Edition" truck. I figured they have them for most states.
California Special has gravitas due to it's history. Not much past when it comes to Florida. Or Texas for that matter.
