If you are parked on concrete and 100% level yes the doors will stay open if not they don't. Not worth having the fridge get all moldy. 2 seconds with the holder and you know it will remain open.
That and depending where your fridge is located in your coach some just do not stay open because they hit a door frame etc.
Ahhh got it. I guess I was thinking everyone has the same setup as I do LOL. The only time for me I shut my fridge off is when I bring it back to the storage yard and it sits level. I Also forgot about not all the fridges are easily accessible.
