I’ll bow to ET’s experience on the fridge plug. I’ve never had an Engel, & assumed that all fridge plugs were much the same. For those folk who do change their (non engel) fridge plugs to Anderson plugs I suppose it may be a wise move to make up a short adaptor cable with an anderson on one end & a ciggy type plug on the other if there is a possibility of needing to plug the fridge into someone else’s vehicle.
