Our country is one big adventure, and you can explore it all with the new Big Country fifth wheel from Heartland RV. Each Big Country fifth wheel is designed with your budget in mind. It is engineered for the perfect balance of luxury and practicality. With the best features in its class, this fifth wheel RV has all the comforts of home with plenty of room to roam. Spacious floorplans deliver a residential look and feel for the ultimate RV experience. General RV offers several unique floorplans to fit every family’s needs, including the popular 3155 RLK.
Feel right at home in the Big Country fifth wheel


Elegance and class greet you when you first step inside the Big Country. Immediately, the all-in-one touchscreen master control welcomes you. It gives you complete control of tank monitors, slides and light switches. On your left, relax and unwind in the expansive kitchen, dining and living space. A tri-fold sleeper sofa at the rear of the RV, as well as power theater seating with heat and massage, provide ultimate comfort around the entertainment center with a 55-inch TV and built-in 40-inch electric fireplace. Super USB charging ports and wireless charging stations throughout the Big Country help ensure your electronic devices stay energized and connected. This is especially useful for larger groups or anyone looking to work remotely. High-end woven flooring in the dining and living area slide outs make it easy to maintain and clean. They are also pet friendly and antimicrobial.
Cook with confidence in the Big Country fifth wheel’s complete kitchen
Complete residential kitchen with designer island




The kitchen may be the true showstopper of the Big Country. The most noticeable feature is the designer island with a built-in, single basin, farmhouse-style sink, roll-up sink cover and residential sprayer faucet. You will feel like you are cooking at home with the 21 cubic-foot residential refrigerator, 30-inch microwave and 3.7 cubic-foot residential oven and gas cooktop. All Big Country fifth wheels also come equipped with a full-size pantry and stained hardwood cabinetry and fascia with soft close cabinet doors and drawers for an elegant feel. There’s even a separate coffee bar area next to the pantry, providing even more counter space to work with.
You’ll also find an abundance of LED lighting throughout to brighten up the interior with a more open feel. The dining table with free-standing chairs offers a comfortable space for eating, playing games or even getting a little work done. A mixture of small and large windows provide expansive views throughout the rear and right-hand side of this fifth wheel.
Sophisticated bathroom design adds style to the Big Country fifth wheel
Full bathroom with primary suite access
To the right of the entrance, a short climb up the stairs will lead you to the full bathroom. The one-piece fiberglass shower with luxury glass surround also features a tall ceiling height of 6-feet 4-inches, adding extra height that is often a coveted feature for many RVers. A large medicine cabinet provides storage for all of your bathroom essentials. The grey water tank capacity of 90 gallons and a 65-gallon, fresh-water tank will allow you to take those extended trips with little worry.
Leisure meets luxury in the RV’s primary suite



Rest and relaxation await in the Big Country’s primary suite at the front of the fifth wheel. Sleep easy on the large king bed. Additionally, storage space can be found in every corner of the primary suite. A wide walk-in wardrobe with sliding glass doors allows you to pack those extra outfits. Also, a large closet provides hookups for a stackable washer and dryer. More drawers for storage are located at the foot of the bed and there’s also storage space underneath the bed. Several windows provide plenty of light during the day and overhead reading lights will keep the room bright at night.
Take home on the road with the Big Country fifth wheel



The Heartland Big Country fifth wheel packs the comforts of home into an easy-to-tow RV with added convenience for your travels. The innovative exterior storage design includes three points of access. This provides easy loading and unloading, as well as ease of access to exterior entertainment hookups. Insulated slam-style cargo doors with magnetic hold backs keep the storage compartments sealed and safe.
The universal exterior docking station combines all hookups, dump valves, flush, cable and satellite ports, shower and winterization access – all in one convenient and concealed compartment. A six-point hydraulic landing gear and auto level system make set-up and tear down a breeze. The dual Whisper Quiet A/C system provides 30,000 BTUs of cooling power. It keeps the Big Country comfortable on the hottest of days. Independent thermostats for each A/C unit allows for personalized comfort and ease of control. Relax with a movie or some music with the high output entertainment system with DVD, HDMI and Bluetooth. Azdel laminated sidewalls with lightweight non-wood substrate provide increased insulation against exterior sounds and weather to maximize comfort and coziness.
An RV built for safety on the road and at camp

Not only does the Big Country fifth wheel take away your worries at the campsite, but it eases anxieties on the trip there, as well. The MORryde 3000 suspension and Dexter NEV-R-ADJUST brake system provides 50 percent better stopping power. G14-rated 16-inch tires with aluminum rims and leaf springs roll down the road on 70,000-pound industry-leading axles with Easy-Lube hubs. Plus, an upgraded Rota Flex pin box works to prevent back-and-forth lurching, known as trailer chucking — an all-too common occurrence for fifth-wheel owners.
