We ordered a 3570 and will be picking it up soon. There is a lot of counter space in the kitchen, a large full door (like on the washer/dryer closet) on the pantry with room for cases of water etc., lots of cabinet and counter space in the bathroom. We ordered ours with the queen bed so the bedroom is easy to get around in and a quality replacement mattress (standard 60x80) can be found anywhere. Also dual pane windows, fireplace, double door fridge, Goodyear G-614's, 6 point level up, mor ryde hitch, power cord reel, etc. As far as I can tell the bathroom in the 3570 is unique to that floor plan in the Heartland line up.
