We bought our 29QBS and it came with an outdoor kitchen standard at the time. We though it was just a novelty, I had plans of taking the outdoor fridge to use in my office, take the cabinets out and use the space as storage and to hang an outdoor tv.
Now I can't imagine a trailer without an outdoor kitchen! We cook breakfast outside ever morning. Bacon and eggs, usually on a griddle on a nearby table, potatoes with peppers and onions on the outdoor stove. No onion or pepper smell sitting inside. No grease splatter inside.
Tacos for dinner? Sure, cook them outside so we don't smell tacos for the rest of the night. Spaghetti tomorrow? Cook it outside so it doesn't smell like garlic for the rest of the trip.
Outdoor fridge so I don't have to go inside and wake the kids while the parents and friends are sitting by the campfire? Perfect!
Outdoor sink so I can wash my hands outside when I put raw sausage or burgers on the grill? Perfect!
Ours is a larger outdoor kitchen with a door that opens up. Its big enough to provide protection from the sun and rain. I love it. Some people don't. To each their own...
