Thank you it was dometic not domestic, darn speech to text.
This is a 1976
Boler, therefore all the controls are on the outside found in the hatch that the vent covers as does the pilot for the
fridge. The vent cover I need has three tabs on the top that fit into slots and two screw holes on the bottom to connect to the vent frame that is found on the
Boler.
I have looked online at Amazon and all the RV parts places to find this particular vent cover. Mine is not hinged
I’m hoping to find the right cover, if not I have to take out the whole frame and put in a new frame with a hinge vent cover. See the in a very primitive diagram.
