The Isotherm 40 Cube refrigerator makes a pretty nice replacement in a Westy. The Samba user, noganav, posted his installation and it’s worth a look. The depth fits perfectly, and you gain space above and below. Noganav made his installation look as stock as possible, and he even installed solar panels on the roof so the fridge doesn’t affect his battery. Not bad.
