My first thought with a silver truck is what pinstripes? Do you know how hard you would have to look to find pinstripes on silver? Not to mention anything that will go deep will just go right through a decal.
I would be more worried about those tube steps destroying your side panels if you ever hit them offroading than pinstripes on a silver truck. In addition, the pinstripes will still be all up and down the rest of the truck, you are only saving a few feet, and only on the spots that has a decal. You will just have patches of scratches instead of full ones.
But hey, whatever helps you sleep at night.
