Most people think they cook more than they do even at home. If someone is cooking like they did in the '50s then that is a true exception today. Those of you who FT and spend that kind of time cooking are few. Efficiency and speed tend to be the norm. Where you spend the most time is where you should dedicate the most space.
The point is that when I DO cook, I have everything that I need to make any meal that I know how to make. I don't have to cut corners or juggle between the small burners on an RV stove.
Other than the stove and ovens, my kitchen includes a rice cooker (Tiger), deep fryer (DeLonghi), waffle maker (Krupp "spinner"), meat slicer, Bosch Universal mixer/blender/juicer/ice cream maker/grinder and a deep freeze (which, unfortunately I can't use except on shore power, though my next solar power upgrade will correct that problem and also give me enough capacity to use my washer/dryer).
From front to back, the ONLY RV part in my entire coach is the fridge (I need to be able to run on propane). Everything else is normal house stuff.
