Mountain Aire 4537

  • Mountain Aire 4537 Floorplan Image

    Quad slide outs, a walk-through bathroom plus a convenient half bathroom, and plenty of "at home" comforts is what you will find throughout this 4537 Mountain Aire motor home by Newmar.


    In the combined kitchen and living area there are dual opposing slide outs which help to open up this space. The slide out along the road side features a hide-a-bed sofa with an overhead cabinet, a hide-a-leaf dinette with a buffet, a refrigerator, and pantry. The slide out along the door side features a 68" jack-knife sofa with a TV, two burner range, double sink, and an overhead cabinet for your dishes. Both the driver and passenger seats swivel around and provide additional seating in this front area.


    Heading toward the rear, the mid-coach bathroom is along the door side. Here you will find a toilet, sink, and overhead cabinet. 


    A set of sliding doors along either side of the walk-through bathroom easily close off this area and create more privacy for you. Here you will find two sinks, a medicine cabinet, a make-up desk and a vanity chair along the road side. The opposite side of the bathroom features a private toilet area, and a 40" x 32" shower.


    In the rear bedroom there is a slide out with a king bed, an overhead cabinet, and two nightstands. Across from the bed you will find a slide out with a dresser, TV, and overhead cabinet. Along the rear wall there is a wardrobe with sliding doors, and a spot for adjustable shelves or drawers, or you can choose to add an optional washer/dryer, plus so much more!


    This model is available with a Spartan K3 chassis.
