Id do an oil change first just to be safe, wont hurt. Then take a look at your spark plugs and wires to see what kind of condition they're in, if need be replace them.
Just do an overall inspection of your new truck, pop the hood see if any fluid is leaking or any belts are worn and need replacing along with gaskets etc.
If you have the money (and if you trust shops) you can take it to one and have them do a complete tune up and flush for you to ease your mind a bit.
