Well, the video doesn't show anything actually did, so no way to tell how it turned out.
Outdoor kitchen... great. If you don't mind cooking when it rains, it's chilly or very hot, a lot of bugs flying around, and going outside when you get hungry in the middle of the night... Shower... much the same.
Personally, I like to do all my bathroom stuff inside. Cooking outside. We do a lot of that outside anyway, but like the convenience of being able to inside for the reasons mentioned above.
But, it's your RV and you can make it however you think it suits your needs and wants. Anything is possible with a little imagination and good pre-planning!
