Wallas Stove.. We have never "winterized" a diesel or kerosene Wallas stove. The evaporation off diesel is minimal. I have purchased used Wallas stove which have not been used in several years, and had fuel in them, which was still fine. I did burn the fuel which was the tank in a land vehicle, and put in new fuel.
We cooked with induction burner for the last few years we owned the C Dory 25, and still cook with induction in our RV which has a propane stovetop. Especially in Florida where it can still be hot at dinner time, the lack of radiant heat in the cabin is a blessing.
