I'm not familiar with your particular model, but I have never seen one that you couldn't get to the refrigerator at all with the slide in. Most are a tight squeeze getting to it, but you can get there. Now, a bunkhouse room sometimes becomes inaccessible with the slides in.

Looking at the Sunset Reserve broschure the illustration of the 29ss should be refer accessable with the slide in. The bunks and bath would be a tight squeeze, however.
