This Keystone Big Sky fifth wheel by Montana features triple slides, a rear living layout, a convenient kitchen island, and HD TV with fireplace below in the living area.

As you enter model 378RL notice the spacious living and kitchen area with dual opposing slides fully expanded. There is a dinette slide out for two along with two recliners to the left of the entry door.

Along the rear wall find an 80" hide-a-bed sofa with end tables and storage above the entire width of the unit. The opposite side slide out features an HD TV with fireplace below, storage, and some of the kitchen appliances.

There is handy floor to ceiling storage as soon as you enter to the immediate left of the door. Straight ahead find the steps that lead up to a bedroom and side aisle bath. There is a corner pantry just beyond the steps for dry good storage, plus a convenient kitchen island in the center of the floor features a double sink, prep space, and a stainless steel dishwasher. Behind the island in the TV slide out find a three burner range, stainless steel over-the-range microwave oven, and refrigerator.

Up the steps find a closet to your left in the slide out that has been prepped for a washer and dryer. Across the hall is the bathroom which features a tub/shower, toilet, and vanity with sink. There is a second bath entry which leads directly into the front master suite.

Inside the private front bedroom you will enjoy a comfortable queen size bed which is part of the slide out that includes a closet. Opposite the bed find a window seat, HD TV, and storage. You will also find a large front wardrobe with sliding doors, clothes hamper, plus so much more!
