Dave, There will be a regular refrigerator in the kitchenette setup located in the barn. The kind that are in our coaches fits under the kitchen counter and are way too small.
Where the coach is parked will have an air exchanger. Keep in mind the lento will be attached to the side of the barn and that means there will be a solid wall between the open living space and the coach or RV. When it comes time to put the full kitchen in place, with a post and beam design; one can plan to be able to remove part or most of the wall between the living space and lento where the RV is parked. One parks there car outside once you take over the lento space for more indoor space.
