Pinstripes, matching the trim color? If you have a steady hand, you can do it yourself, and get the stripes at Walmart, or an auto parts store.
Also, when you wash/wax the truck, be sure to use a good tire treatment. Clean, shiny wheels/tires make anything look better; especially a black vehicle.
Another little trick, when you wax the body, also wax the glass. Seriously, assuming you're not using a "colored" wax. It works like Rain-x, but better; and it lasts longer. It also makes the glass look cleaner/shinier. Just be sure to buff it out really good to avoid streaks/smearing.
