Fridge Venting

Hello all!

I'm in the process of doing a frame-off restoration of a 1977 13' scamp and have a questions about the venting needed for a fridge. I currently have two holes from the previous venting from the 3-way fridge, and am unsure if two are still needed, plus i'm having a hard time finding new vent covers that will fit. I can imagine that the newer technology of the current fridges need less venting than this one has. Ive been glassing in the old holes from the heater, the stove hood, and overhead vent, so glassing these babies in, and cutting only whats needed for venting is an option. can anyone weigh in on how much is needed for proper ventilation, and if this is a waste of time to do?

it depends on the fridge you are putting in, find the fridge you want, look up the manual on the manufacturers site, and it will give you the venting options and sizes

Most fridges, either 2/3 way or 12 volt compressor, require separate vents. The size is dependent upon which fridge. The bottom vent pulls in cool air and the top one exhausts the warm air. With 12 volt compression fridges, you can have both vents on the inside of the trailer since there are no combustion products to be concerned with or you can stick with venting outside the trailer. If you choose the latter with a compression fridge, the vent openings in the shell may be smaller than what you have now allowing for different vent covers to be used.

I don't think new absorption fridges have really changed all that much, believe it or not. Venting is still crucial, and still requires big holes.
