I saw a badass murdered out 25 or 26 Maverick today in Yakima. It had an all black cap on it with no windows and the Raptor style lights in the grill. It looked great. I didn't have a chance to snap a picture.
I bought an aluminum roll up one on Amazon. I really like it. The main thing I don't like about it is that it's not flush with the bed rails. Otherwise it's great. If I were to do it all over again, I would make sure it was flush.
