I use the little plastic latches along with a kitchen towel wedged between the fridge and freezer doors. Too many times I've found my fridge closed up tight despite using the little clips after a short drive. So when I get to storage, I open them ALL the way and wedge them against the bathroom door. I just close them back up as part of my prep routine when I go retrieve it from storage so they're secure while under way.
