Forest River Sierra Destination Trailers 40DUPLEX highlights:

Two Loft Areas
Bath and a Half
Dual Entry Doors
Hidden Shelves behind Fireplace
Shower with a Seat

You won't believe the comfort and convenience found in this destination trailer. There are two private bedrooms; one up front with a queen bed slide out and storage space, and one in back with a queen bed slide out and a half bath! There is even washer and dryer prep here if you want to add those appliances and the second entry door is also found in this location so you can easily slip out in the morning. Above each of these rooms is a loft providing three total bunk mats for sleeping, storage cabinets, and TV prep in the front loft if you want to add entertainment. Everyone can meet in the combined kitchen and living room that includes dual opposing slides, theater seating across from a 50" flat screen TV and fireplace, plus a free-standing table and chairs to dine at. The chef of your group will love the large kitchen island, 3.7 cu. ft. free-standing range with four burners, and a 19 cu. ft. 12V stainless refrigerator for food storage.

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!

Just wanted to thank Mitchell Zimmerman for all of his help throughout our first camper purchase. He was fantastic! Hope to do business again!

Thanks Andy and the RV Value Mart Team
On our way back to Maryland from a summer trip in July we had a catastrophic failure on our old travel trailer toy hauler, on a whim we decided to stop into RV Value Mart which is where we met Andy Starke. He took the time to walk us through several new RV's and there was no pressure to buy at any time.
