I own a black double cab. If I were you, I'd just go with the regular premium tint they have out today (not the reflective kind). I'm not sure if they still use that crappy tint that turns purple over a year or 2, so make sure you don't get that cheap tint.
I had a factory tint of like 35% (someone correct me if I'm wrong) on the back windows and no tint on the front two windows when I first bought my truck. So I had the tint shop put 20/25% on the back windows ontop of the 35% and 15% on the front windows and on the "brow". I think it looks great. Here's what it looks like ---
(I think they look darker than they really are in these pictures. During the day, the front two windows you can see a silhouette of the people inside, and the back windows are pretty much blacked out.)
