We have looked at a few Pinnacles. The oven / stove was made by Atwood. The microwave was Samsung in some and Frigidare in others. Those that had the smaller refrigerators had Norcold. Otherwise, the residential style refrigerators were Samsung from what I recall. Although, I could swear that the manufacturer varied on the refrigerators if I remember correctly. I'm not sure why and thought they'd all be from the same manufacturer.
