We have only been out for 2 nights on a shakedown cruise. So far we love the 303RLS. You can get to the fridge, bath and bedroom with slides in.There seems to be plenty of counter space, at least for us. Pictures on manufacturer website are really what it looks like. If you get one made Nov or later it should have the mod to allow for 16" wheels. See my Maiden Voyage post in the fifth wheel forum for a couple of pictures.
Grand Design has changed the bedroom dresser configuration to 2 closets. It was a surprise to us at PDI, but we like it. I included a picture of this in my post on the Grand Design Owners Forum
