Move from the frozen tundra to Texas although you will start asking air conditioning questions quickly! We bought a small ceramic heater at Walmart and use it rather than the propane heater that came with the trailer and this small electric heater keeps the whole 5th wheel as warm as you would like. The idea about the inside of cabinets is a good one as there is NO insulation behind our kitchen cabinets. In a void like where our water pump is, there is a thin piece of wood covering the opening and that void gets REAL warm so I am thinking some insulation in those areas might not hurt be it for better heating or cooling.
