I gotta agree. Go with the body color. I'm curious to see what it would look like, but with a lighter colored truck like yours I think it would look awesome!
If the truck were a darker color (like green or blue) I'd have to say go with black

 

yep i agree totally with you sisk. my friend owns a paint/body shop so im gonna have him paint it and smoke my tail lights too.

 

Nice! I love smoked out lights. I'm thinking about doing mine.
