I own a 2008 view 24h. Yes the couch can be opened with the slide in. It bumps up against the dinette though so there will be no aisle. Not a biggie unless you also have folks in the overhead bunk; they will have to crawl over you to use the bathroom if needed at night.
We are happy with our 24h. It's the best floor plan for our family.
