I installed some modified bed side trim across the back of the cab at the two tone paint break line.
Pretty subtle, not very noticeable in the photos below, but it visually ties the custom cab b-pillar trim panels together.
I also mocked up some side trim on the truck, just to get a visual of how it would look. I am still 'on the fence" as to if I want the trim at all.
I personally like the short spear look vs. the long stock spear.
