Forest River Sierra Destination Trailer 401FLX highlights:

Dual Entry
Theater Seating
Kitchen Island
Recessed LED Lighting
50" Flat Screen TV
Hide-A-Bed Sofa

Now you can enjoy your family vacations in complete comfort with this destination trailer. The kitchen includes an island, plenty of counter space to cook meals, and a large pantry for dry goods. The fireplace and 50" flat screen TV, along with theater seating and a hide-a-bed sofa make for a cozy evening indoors, and the free-standing table and chairs allows you to dine like you do at home. After a day outdoors, clean up in the full bath that includes a shower with a seat, then head to the rear private bedroom to bed. Here, you'll sleep soundly on the slide out king bed, and if you want to always have clean clothes throughout your trip, consider adding a washer and dryer to the space that has been prepped for both.

With each Sierra Destination Trailer by Forest River you will enjoy many luxurious features, such as crown molding over the kitchen cabinets, solid surface kitchen countertops, a memory foam mattress, plus so much more. The extra large picture windows throughout let natural light in and provide beautiful outdoor views, and each model includes three or more slides for added interior space. You'll find many exterior conveniences, like the porch light with an interior switch, the rain gutters with extra long drip spouts to prevent black streaking, and an electric awning with LED light strip, plus more! You will stay comfortable year around with dual 15,000 A/C units and the high-efficiency radiant foil in the roof and floor, plus each model is constructed with an Underbelly Armor for better insulation!

Great experience

Eric from Dover, PA
We had a great Experience
We had a great experience at RV Value Mart! We went in looking for a used camper and ended up purchasing a brand new camper for close to the same cost. The staff is knowledgable and helpful. Awesome experience and we will definitely be return customers!

Vince from Jersey City, NJ
Brandon
Brandon was straight forward, answered questions and gained my trust, which is not always easy when it pertains to sales. Looking for a trailer I did much shopping on line, and some in person. Everyone is busy so I utilized email to ask questions on several units. The best at getting back to me was
