The 222VIK does have passthrough storage.
I wouldn't also own any trailer with opposing slides that when both stored in the travel position block access to many parts of the interior of the trailer
That's personal preference. My KZ Durango opposing slide model blocks the kitchen when closed. I have no problem opening the slide about two feet or so to allow access to the fridge while stopped for a break or opening it up all the way for lunch. It's really not as big of a deal as some seem to make it.
YOUR trailer is the one that makes
YOU happy!
To date I have owned two KZs and a Keystone. I'm staying with KZ.
