Gateway 3712RDMB Fifth Wheel Bunkhouse/Den

There’s no place like home and with the 2017 Gateway 3712RDMB, home is where you park it! This 5th wheel has a large living room, well-equipped kitchen, a dual purpose bonus room, and a comfortable master suite. All of these areas are jam packed with features to keep you comfortable and happy the entire trip. If you’re wondering why you don’t see pricing for this model we’ll let you in on a little secret. With our factory direct discounts that save you thousands, our pricing is so low Heartland made us promise not to put it on our website. Check it out!

Heartland Gateway 3712RDMB Layout

The 2017 Gateway 3712RDMB has a rear living room with dual slides. One holds a small sofa while the other is larger, holding another small sofa, the dinette, and refrigerator. These slides really open up the living area, allowing for plenty of furniture and seating space. The kitchen is connected to the living room and has a U-shaped countertop so you’ll have lots of workspace!

The center area of the 3712RDMB is the most dynamic area. Depending on what your needs are, it can be used as a bunkhouse for kids or a relaxing den area! There’s a slide in this bunkhouse/den area that opens it up to give you more floor space and a loft overhead offering added sleeping space! Your own master bedroom is found in the front, that also holds a slide. The bed is contained in the slide, creating enough space for storage at the foot end!

Whether you’re here in the mitten, in the sunshine state, or up in Canada, you can still take advantage of our amazing price on this model. We offer worldwide delivery and many customers find that even with delivery, they’re able to save more than with the local dealer!

Heartland Gateway 3712RDMB Features

Exterior/General Interior

  • High gloss sidewalls outside are easier to keep clean and shiny as they’re not porous like the matte finish so there’s nowhere for the dirt to get stuck.

  • With R-11 insulation in the walls and R-38 insulations in the floor and roof, the interior will stay the temp you set without allowing as much heat transfer!

  • Winter camping is a go! A 35K BTU furnace, 12 volt heat pads on the holding tanks and enclosed tanks & valves with a seamless underbelly panel allow you to head out keeping the inside comfortable and prohibiting your tanks from freezing up!

  • There’s no worrying about popping breakers just from using the A/C and microwave at the same time. A 50 amp detachable cord brings enough electricity in to handle it all!

  • Inside your full pass through storage area you’ll find a pet connect that lets you anchor a leash for your fuzzy buddy to hang out outside with you when you get to your site.

  • Residential flooring runs throughout the interior so it’s strong enough to withstand the test of time.

  • There’s no more sweltering when the summer sun gets hot. Fire up your “Cir-Cu-Lair” air conditioner that consists of dual A/C units and two thermostats that offer up 28.5K BTUs of cooling power!

With all these features and available options, you can find the RV that’s exactly what you want. We have a huge selection on our lot and if you don’t find what you’re looking for already here, we’ll custom order it for you!

Main Living Area

  • With the solid surface countertops in the kitchen, you won’t have to worry about bacteria hiding in them! They’re non-porous so there’s nowhere for it to hole up!

  • The stainless steel appliances include a spacious residential refrigerator to stash cold items and a 3-burner range with a large 22” oven for making all your favorite cuisine!

  • Serve up those home made dishes at the free standing dinette that’s easier to get in and out of than a booth.

  • When you’ve run out of steam and need to decompress, there’s plenty of room on the comfortable sofas in the living room to relax and watch the large HDTV that pops up from behind one of the sofas!

  • If you have someone wishing to spend the night, additional sleeping space can be found in the sofa sleeper in the rear!

Bunkhouse/Den/Master Suite

  • The main area of the middle room offers a sofa sleeper great for sitting during the day and folding out into a bed at night. With a loft overhead, there’s even more sleeping space!

  • The oversize shower gives you that home like feel when you’re getting cleaned up and ensures you never have to chance the conditions of the campground bathroom ever again.

  • You’ll find a solid surface countertop in the bathroom as well! This thing is so durable, you can set your hot curling iron on it and it won’t phase it!

  • A massive walk-in wardrobe lines the front wall in the master bedroom and is prepped for the easy addition of a washer and dryer, keeping you from having to make a trip to the laundromat!

  • When the day is done you can crawl into your own queen (optional king) bed and feel the comfort of the soft pillow top memory foam mattress that will deliver the great night’s sleep you need to do it all again the next day!
