It does have some nice upgrades from the 295rst (as mentioned bed slide, bigger shower, nicer lighting above the island and option for w/d) but at the expense of weight and length. Mostly because of where I live (high passes every trip and special license required for over 10,000lbs actual weight) the 295rst was and is a better choice for us -but can see the 315rst working for others. The touring edition is the way to go. Try and get the 16 inch wheels/tires and dual pane windows.
