We hope to use the kitchen in the RV to cook. Inside the barn home, we’ll have plumbing and wiring on the one outside wall to hook the coach too. We will have a small kitchenette setup with a microwave and larger refrigerator in the house. I’ll be able to add the kitchen in the barn house; once we are not able to drive any of our RVs anymore. That way we save from having to buy kitchen cabinets and all the appliances right away.
Of course the you need to have positive flow venting for any gas appliance, including the fridge. You kind of have a problem in that the fridge is ammonia. If the cooling unit bursts, normally that vents to the outside of the coach. If the outside of your coach is inside your house, you will die.
