CHEFS KITCHEN PACKAGE

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, rods to hand clothes, and baskets for laundry! There is a unique middle utility room with washer and dryer prep and a rod to hang clothes 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 high output range with a 22" oven, plus a large counter with barstools where you can enjoy breakfast at each morning. Choosing this fifth wheel is a no-brainer!

Each one of these Forest River Sierra fifth wheels are equipped with everything you need to make the most of each adventure! The underbelly armor will protect your unit's vitals from road debris and the painted two tone aerodynamic fiberglass front cap has an improved turning radius to make them easier to navigate. With an electric leveling system, you can set your unit up quick and easy then get to having fun faster than ever. The welded aluminum framed, vacuum bonded laminated superstructure will hold up through every adventure and the cambered powder coated frame comes with rust prohibitor to last longer. Each model also includes the Summit Package that comes with a king Wi-Fi extender system and Olympus antenna, a full coach water filter system, Goodyear tires with 7,000 lb. axles, and the list goes on. The interior is just as impressive with rustic wood plank linoleum, recessed residential lighting, a memory foam mattress, and mocha accent crown molding over the kitchen cabinets!

Best Price. Best Service.

Best RV buying experience!!
Best RV buying experience!! Their list prices are excellent so no need to haggle a lot on price. I felt they gave me a very fair deal on our trade in as well. The buying experience was so simple and they made sure to provide our RV in perfect condition. Anthony Webb was always available, quick to respond

Fantastic group of people.
I want to say thanks to a great group of people at Zoomers in Wabash Indiana. TJ was still new to the company, but was straight forward with us. The girl at the front desk was a pleasure to work with. Finance department was fantastic. The girl giving us the rundown on our camper was great also.
