Ok, I understand you're asking for everyone's opinion, but what really matters is who cares what WE think. What really matters is what looks good to you. Everyone has their own uniqueness and it shows in our trucks. If they all looked alike it would'nt be as much fun to look at them. As for me I think your truck looks great with or without cowl, roof looks good as is and would look good white, it looks great with the wheels you have and would look good with many other styles as well. The only thing I think is throwing off the look is black out in front and white letters in back. But as with everyone else on here that's MY opinion, and if you decide to put pink letters out I would be happy for you, because you are enjoying your truck.
BTW we do want pictures if you change something.
