The outdoor kitchen was one of the reasons we purchased our Winnebago 2201DS.
The small bar fridge is our primary drink cooler which saves a lot of room in the main fridge. Whenever possible, we would rather do our cooking, or most of it, outside. Our Weber grill is set up adjacent to the two burner stove and it is easy for me to monitor the grill while I use the stove for cooking whatever is going to accompany the main event! My DW will prepare salads at the inside kitchen and take care of any vegetables that are cooked in the microwave (we use of a lot of the frozen veggies in the steamable bags). Since we are getting older, if the weather is foul and for many breakfasts, we use the indoor galley. But, if possible, we would always prefer having the outdoor kitchen. If we were to purchase a RV without one, I would want an RV that would provide a storage area for a bar fridge, and improvise a outdoor kitchen.
