Ours is not a full kitchen. It's a drop down sink and 2 burner stove. Considering we do almost 100% cooking outside, yes, it get used a lot. We don't really have a need for an outside refrigerator. We do have a Coleman electric cooler. On it's back it's like an ice chest, on it's end, it's like a small refrigerator. Works great for us. But, it usually stays inside the camper, very rarely do we take it outside.
Would I want a full outside kitchen? Nah. The pop-down sink with hot and cold water (attached to a yard sprayer) and the 2 burner stove works very will for us.
The hose with yard sprayer works great for an outside shower too.
Ours is under the awning. It takes very little space away. We usually set a table under the drop down so when doing dishes, they can sit there an air dry.
Not my camper (my photo), but it's identical to this:
