    Floorplan - 2015 Tiffin Motorhomes Allegro Bus 40 QBP

    This Allegro Bus class A diesel coach 40 QBP is a whole lot of luxury on wheels just waiting to take you someplace special!

    As you step inside you will be amazed at the beauty that this coach exudes. With quadruple slides you know that there will be plenty of room inside. So, step up three steps and take it all in! Even the cab area will make you feel like you are being pampered with ultra leather driver and passenger seating, plenty of storage in the overhead cabinets on each side, and there is a TV in the overhead compartment for your convenience.

    Move into the wide open living and kitchen area with double slides opposite one another. There are sofa beds in both slides facing one another which makes a great conversation area. And there is a flat screen TV just beyond the slides that can be viewed easily from anywhere in the room.

    The kitchen amenities make meal prep and cooking feel just like home with a residential refrigerator, range with microwave oven above, double kitchen sink for easy cleanup, and plenty of counter space and storage in the ample overhead cabinets. You can even add a drawer type dishwasher for convenience. Now that is luxury on the road!

    Opposite there is a dinette with computer workstation for meal times, or for when you need to do a little work while you are away from the office.

    Heading back toward the rear of the coach you will see a convenient half bath with toilet and lavatory sink plus overhead cabinet.

    The master suite starts with a slide-out queen bed, or optional king, plus there are nightstands on both sides of the bed. You also have a large overhead compartment for storing some of your things. Opposite the bed is another slide which features drawers with more storage above, and a TV in the upper corner.

    The very rear of the coach features a full complete bath with corner shower, toilet, and vanity with sink. There is a full closet and optional washer and dryer if you choose to add it also.

    Besides all of the luxury you see inside there are even more conveniences you can add or select that will make this Allegro Bus feel more like your home. You can add an optional fireplace below the living room TV, a u-shaped dinette, two ultra leather recliners, or maybe just one ultra leather lift recliner with flip-up table plus a corner entertainment center with fireplace. Choose a king size bed in place of the queen, an exterior TV for when you are enjoying the outdoors, or even a drawer type dishwasher and more!
