Ford has had the best selling truck for many years. I believe Ford's marketing strategy has been more successful. Anecdotally, Chevy/GMC has a reputation, and I'm not saying it's deserved, for having interiors that look cheap. Dodge has a good reputation for strong motors but bodies that don't hold up. Again, I'm not saying it's a deserved reputation. And, although I currently own a Ford, I'm looking to upgrade and I'm seriously considering Chevy/GMC or Dodge 2500hd or 3500hd models since their diesel motors (by reputation) are better than the Ford 6.0 in the years I'm looking, 2004 to 2007.
