My previous 5th wheel had an outdoor kitchen equipped with a sink, fridge, stove and a second microwave. To me the issue with the outdoor stove is that it was still connected to the rig and it made a big as mess as cooking indoors. Our current rigs outdoor kitchen has a sink, TV, and good size fridge. No stove and no microwave. We set up a table with the bbqer and a single burner stove for cooking outdoors. Other than that we cook inside just like at home.
I like having a fridge and tv outside but I could live without it as well. I've seen some people renovate their outdoor kitchen into more storage or even a laundry. Atleast you can have options if you don't like it.
