Outside rear clamshell kitchen like on teardrop campers

Forest River makes the R-Pod, a 20' with what they call the "Rear Garage" It is a tear drop type space with a "utility" sink. I have seen that used for outdoor cooking. It does not have a stove or refrigerator in the rear garage, but does have a galley inside.

I simply set up an outdoor kitchen on the picnic table and do 90% of my cooking outside. The oven or microwave may get used once in a while.
