Another suggestion - Don't limit yourself with the existing floor plans. Phoenix Cruiser is very willing to work with the customer to give them what they want. Check out what George and Judi designed for themselves http://www.phoenixusarv.com/community/index.php/topic,434.0.html
This is the only way I would personally have a unit without a slide. We sat in their unit and there was plenty of room for four of us. We have also sat in the units without a slide and just a dinette or just a couch and we would never go that route. But everyone is different, everyones needs are different and you need to consider what is going to work best for you.
