I am gm truck till I die, but I feel like MANY aspects of these 2014s were borrowed from other trucks...

The Silverado cab resembles the dodge cab...





The Sierra front end looks a lot like the F250 front end when it's all chromed out...





The tailgates look just like the current F150 tailgates and resemble the Dodge tailgates as well...





and I think that the "crew cab" looks very similar to the dodge as well!
