When traveling, is it ok to have the outside fridge packed? Even though they are AC only, I'm sure they would stay cold for several hours. I'm thinking things like water, soda, beer. Things like that or would I likely find the contents all over the place when I open up the kitchen door since it's just the door seal keeping it closed? I could install a latch or put a bungee around it but I really don't want to do that.
