Locked inside by entry assist handle

On mine, even if it is folded toward the door, if you push the door hard enough, it will pop it back out. If you look at the design, it is sort of beveled so it will slide back out if you push hard on it. I tried it on my last rig, even though we had a back door.

Try it from the outside....close the handle then pull straight out on it. IT will jump over the beveled area and open. And testing it this way will not leave a mark on your door.
