3100 Slide ?

In every floorplan I've seen, the 3100 sofa area is on a slideout.  But when pricing one out, it shows sofa/slide as an option(about 4k). Does the 3100 come basically w/o a slideout?  Seems a bit odd to me that everything would show that it has a slide if it isn't a "basic" item.  Also, is there a door/divider between the BR area and the kitchen area?  Is it a door, or a accordian type divider. 

Thanks

We have a 3100 with a slide. I’m sure it’s an option, but I can’t imagine not having the slide – what a difference when it’s out! And you’ll get a lot of that cost back when you sell it. So in the end, the cost is not that much more.   

The door between the dining/bedroom areas is of the accordion type, mainly because the passenger side bed is slightly longer than the driver side bed and the door closes at a slight angle. It’s never been a problem for us. We’re now in Florida for a month, and I close that door when I get up in the mornings
