I also have a Sunset Trail with an outdoor kitchen and use it exclusively as I don't like to odor up the inside of the TT. Bacon smells great but the smell for days is not something I enjoy plus the steam for boiling water and grease from cooking over time can make a mess . The outdoor sink is great when eating outside, which is why we go camping, and washing hands and utensils. The small refrigerator keeps less traffic running in and out of the TT for beverages, and condiments is also a plus. Plus there is plenty of storage, at least in my version, with the pass through compartment and pantry inside.
To each his/her own but DW and I love our outdoor kitchen.
