The two tone look plays into its ruggedness.I don't think many trucks can pull off the two-tone look, but it works on the Rebel. It's different, and I've never owned a two-tone truck, so I'm excited to go with the two-tone option. I think it adds a bit of road presence too.
From a design standpoint, the line through the side of the truck will reduce the visual height when viewed from the side. I think that enhances the design.
