If you've been looking to upgrade your motorhome, this Cornerstone will be the perfect choice. There is a bath and a half, four slides, and sleeping space for four. Once you arrive at the campground, relax on the power theatre seating that is directly across from the 50" TV on lift. You can play a game at the free-standing dinette, or you may just want to head outside since there is an outside entertainment center. The master suite includes a king bed slide out, dual wardrobes, plus your own 43" TV. And check out the full rear bath that includes a rear walk-in wardrobe with plenty of storage space and a washer and dryer.
Each Cornerstone Class A diesel motorhome by Entegra Coach is packed with luxury features to make each trip memorable! The Spartan K3 raised-rail chassis provides a strong foundation, and the Cummins 605 HP engine can power your many excursions. You will appreciate the collision avoidance system with collision warning, adaptive cruise control, and electronic stability control, plus there are six HD cameras included in the surround view system for easy maneuvering in and out of campgrounds. The interior is designed to make you feel at home with premium leather Crown Compass furniture, hand-laid porcelain tiled floors, a Personal Comfort A5 king-size mattress, and many more residential features. Additional features include a portable Shark vacuum cleaner, an Aqua-Hot 600D hydronic water and heating system, stylish interior decor options, and more! The luxury-packed amenities don't stop there! Outside you'll find a heated exterior utility center, two power slide out basement storage trays, (2) 200W solar panels, and hot and cold water hook-up in the front cap area with a 30 ft. quick-disconnect hose so you can easily keep the front of your unit clean!
