I work at a store and make automotive and custom paint, so i can tell you WILL be able to get it matched PERFECT. Basically go to any decent body shop or paint suplier with your truck (clean) tell them the year and paint code (or they can look) im not sure on that new of a dodge, but it is probably on the radiator core support. They will have "varient" paint chip decks to compare to the paint on your truck. Pewters and silvers usually have the most varients to compare, IF theres none that are close, you can have the paint scaned, I have a camera by PPG called a "prophet" that makes up a formula just by taking acouple pictures. Also depending on if the whole panel is being replaced/painted or just an area, you will more then likely have to blend the paint. but if everthings done right, no one will be able to tel, even you.
