I have a related question. New to me Newmar rig with dometic fridge. I am used to the fridge door have a vacuum after opening and then closing the door and trying to open it again should be hard to do. The new to me rig, the freezer seems to be that way, hard to open after having opened it but on the fridge, it clicks closed but does not have that vacuum. Food is keeping cold, the fins do have some condensation on them and the drip tray has some drips in it, nothing terrible but just wonder if this is ok or should I need a new gasket or ???
