On our former AS we did have the reefer door pop open on the road. Actually a couple of times. It had a snap lock but we needed to consciously make sure it snapped securely. Or else. You get the idea. Fortunately it was never catastrophic just minor clean-ups. Our newer AS is a bit better and more secure but we use a bunji cord as insurance and are much better off because of it. We've had things move around inside but never any tippage or breakage. We do try to pack it carefully but so far so good.
