Yeah, you're talking about different eras. I prefer the Art Deco trucks because I like the style and curves of the body and fenders in that era. The Advanced Design are bigger, but they're too prevalent (I like something that's rare and different, which is why I bought my GMC), and the shape isn't quite as appealing as the Art Deco's. The newer they get the less I like them, as they lost that shape from the older era.
