Two inches is one large gap! If it was a small crack you can usually adjust the striker on the door jam to make the door come in furthur before it actually latches but you are never going to make that kind of a gap up with minor adjustments. i would venture a guess that water has gotten into the door and the backing material has curled outward. I would call Kermit/Amanda and have them send you a new door with the matching paint for your year and have a body shop paint the door. Putting the door on is not that large of a deal or you could have any RV dealer or body shop put it on for you. You really need to have it fixed for safety purposes. Best of luckThank you..Thank you
