Welcome to the Forum!
As a fellow new 2014 4R owner, I can guarantee you will throughly enjoy everything about you new truck.
You will have time to think about that first oil change. It is 10,000 miles away for you. I am almost there at 8800 miles. From what I have read, stick to what Toyota recommends for oil. It is the fool proof and the unflashy, fool proof way to go.
And, of course, we all want to see pictures of your new ride!
