Welcome to the forum. We pick up our new 2500TSF Tuesday.
Open the door and look carefully at your door frame and see if the door is rubbing the paint. If it is you might be able to shim the door, to re-square it, to help cure the noise.
Also use a good rubber preservative, like 303 (See Here
), on the door seals. That can help as well.
As SeaDog suggested some thin rubber seal may also cure your squeak. I would add it to the door, instead of the frame, so it is out of sight if I went this route...

It is better to have too much truck than to have too much trailer.
