If you're looking to go full-time RVing, this fifth wheel is packed with convenient features! The master bedroom includes a king bed slide out with USB ports on either side of the bed so you both can charge your phones, and there is a dresser for your folded clothes. You will love the front bathroom with dual bath sinks, a shower with a seat, plus a walk-in closet with shelves! There is a unique middle utility room with washer and dryer prep and a counter that will make a perfect laundry room, or you can utilize this space for storage! Head to the main living area to relax on the theater seating or hide-a-bed sofa, and if you have guests stay over, they can sleep here. There is also an entertainment center with a 50" flat screen TV, but you might just leave that off if you're working at the desk with a chair that is provided. We've saved the best part for last; the kitchen! Here, you'll find ample counter space to prep home-cooked meals, a three burner range with a 24" oven, plus a large counter with barstools where you can enjoy breakfast at each morning. Choosing this fifth wheel is a no-brainer!

You will find the perfect balance of size, space, features, and luxury with any one of these Forest River Sandpiper fifth wheels! They are constructed with a welded aluminum framed vacuum bonded laminated superstructure, a cambered powder coated frame with rust prohibitor, and a fully enclosed underbelly for added protection against the elements. The large tinted windows come with a 80/20 UV prohibitor or you can choose the optional dual pane windows. Some hassle-free amenities include a 60k BTU on-demand water heater, full coach water filter system, tire pressure monitor system, and an electric leveling system! Inside, you'll enjoy stainless steel appliances, solid surface countertops, Beachside Sundance linoleum, recessed residential lighting, and many more comforts!

Knowledgeable and Confident!

I contacted RV Ready, online, after hours and was contacted the next day by a wonderful sales person, Lisa Flach. I had an idea of what I wanted and she had those units in stock. We scheduled a time for me to come in and when I arrived was met with attitudes and an atmosphere that was very comforting

Wesley
