I have a Scamp
13 that the previous owner took the icebox out of and installed a thermoelectric fridge
(about 100 watts). It does a good job of keeping cold food cold, but it also really heats up the inside of the cabinet and, eventually, the inside of the camper.
Eventually, I plan to put a 2- or 3-way fridge
in, but right now, the cabinet is not sealed (the under sink portion is in the same air space as the under stove/fridge space). I bought a period-appropriate Norcold lower vent and plan to cut the hole... if that's what I need to do.
How should I seal up the fridge compartment?
