I have a very similar floorplan, kitchen is situated slightly different and my wardrobe is not part of slide out. I love, love, love my floorplan. I choose the floorplan with the wardrobe not part of the slide, because there was a big difference in price (that one had several other extras too, wish I had but really didn't want to pay for). One thing that plan has that I really wished mine did, is a table at end of sofa. It is nice to have somewhere to sit a cup/glass while sitting on sofa watching tv.
do as suggested and spend a little time in it.. sit on the sofa like you are watching tv for 30 minutes or an hour. My jack knive sofa is not comfortable for sitting for an hour or two.. I end up piling up several pillows off the bed to lean on and sitting side ways.. It is more comfortable, since I have a small ottoman that I can prop my feet on when I am sitting. you will have to make the decision for yourself.
