Here, you'll find a 40" x 30" shower with a seat and two wardrobes for towels and clothes. And don't overlook the master bedroom with its king bed slide, dual shirt wardrobes, a dresser, plus a Samsung LED TV to watch movies in bed!

The Freightliner Cascadia chassis provides a strong and durable foundation to your coach, and there is a 30,000 lb. rear hitch for towing your family car along. A full-paint Masterpiece Finish with cut and buff is ultra sleek, and the smart level hydraulic leveling jacks with a Bluetooth compatible touchpad will have you set up at the campground in no-time. You will stay powered up by the eight 6V AGM house batteries, 12.5 kW Cummins Onan diesel generator, and 3000W Pure Sine inverter, plus there is an energy management system to monitor power usage. There are super polished solid surface countertops in the kitchen, bedroom, and bathroom, and you're sure to appreciate the electric radiant heat installed below the floor tile for added comfort. Additional interior comforts include an Aqua Miser shower system, air ride captain's seats, a plush pillow top mattress, a central vacuum with a tool kit, and the list goes on!
