From the innovative design of the rear kitchen to the well-thought-out living spaces, this fifth wheel delivers an exceptional experience whether it’s being used for full-time living or camping. Join us as we delve deep into the remarkable features of the Keystone Montana 3901RK.

Rear Kitchen Design

Kitchen in the Montana 3901RK

The Keystone Montana 3901RK showcases a well-executed rear kitchen floor plan, distinguishing itself from other similar rear kitchen models on the market. The kitchen itself is full of well-thought-out features:

  • From the sink, the rear kitchen offers an unobstructed view into the living area while an elevated splash wall provides a clear separation between the sink and the theater seats below.
  • Most rear kitchen models have opposing kitchen slides, but by only utilizing one slide in the kitchen, Keystone has optimized the countertop prep space.
  • Thoughtful touches such as power outlets at countertop level for countertop appliances make the kitchen very functional.
  • The kitchen features ample cabinet space including a large pantry and a tall closet with an outlet in case you need to charge a battery powered vacuum. The cabinets are all soft-close with magnet clips instead of the cheap clips typically used in RVs.

Depending on how you prefer to use this RV, you can choose between an 18 cubic foot residential and a 20 cubic foot 12-volt compressor fridge. To help power your refrigerator, every Montana comes with at least a 2,000-watt inverter and a solar package.

Spacious Living Areas

Extendable Dinette in the Montana 3901RK

The Keystone Montana 3901RK boasts a middle living area that deviates from the common theater seat and double hide-a-bed configuration. Instead, the Montana 3901RK features a dining table and chairs.

This seems to make much more sense as the coach is designed primarily for couples that don’t require all that couch space. The dining table can be adjusted to accommodate 2-4 people, making it a very versatile feature.

The electric powered theater recliner seats in the living room have heating and massage features, so you can relax comfortably. From wherever you’re seated in the living room, panoramic windows allow you to enjoy the beautiful scenery around you.

The 4K Smart TV sits mounted above an electric fireplace, creating a welcoming and entertaining space for relaxation. Above the TV you’ll find additional cabinet space to store your belongings.

Well-Executed Bathrooms

Spacious Half Bathroom

One of the highlights of the Keystone Montana 3901RK is its exceptional bathroom designs. This floor plan features a conveniently located half bath off the hallway behind the entertainment center. It’s so well placed, you may not even notice it.

Unlike many other models where the half bath is integrated into the kitchen and has barely enough elbow room, the Montana 3901RK ensures both privacy and spaciousness. The half bathroom is HUGE in comparison to other half bathrooms in the RV industry.

It includes loads of cabinet storage, and plenty of elbow room. Guests will appreciate the comfort and convenience of the well-designed half bath, which can easily accommodate their needs.

The front bathroom is also extremely well executed. The shower gives plenty of head room to even those who are taller and includes a height-adjustable shower head. The vanity includes two sinks and an ample amount of cabinet space.

Impressive Bedroom and Walk-in Closet

The front bedroom and closet in the Keystone Montana 3901RK are truly impressive features of this fifth wheel. The bedroom offers a spacious and comfortable retreat.

The opposing bedroom slides create a generous living space. The king-sized bed is standard in the Montana 3901RK, and it sits across from the spacious dresser and 4K Smart TV.

The massive walk-in closet provides you with ample storage space, allowing you to keep your clothes, accessories, and personal belongings organized and easily accessible. One of the unique advantages of this closet is its ability to accommodate a stackable washer and dryer without compromising hanging storage space.

Thoughtful Details and Considerations

Keystone pays attention to the little things that enhance the overall RVing experience. The Keystone Montana 3901RK is equipped with several additional desirable features, including:

  • A 12-volt ceiling fan and 12-volt rain-sensing vent fans throughout the RV for optimal ventilation.
  • Ample storage options, such as drawers, soft-close cabinetry, and a tall cabinet with a built-in power outlet.
  • Flexibility in refrigerator options, with a choice between an 18 cubic foot residential refrigerator or a 20 cubic foot 12-volt compressor fridge.
  • Inverter prep and multiple solar package options, making it ideal for long-term stays at parks.
  • Central vacuum cleaner system for easy cleaning and maintenance.
  • Blade Pure air conditioning system with residential air filtration for superior air quality.
  • A MASSIVE storage area with a storage drawer in the back of the RV beneath the kitchen.

While the Keystone Montana 3901RK does include many impressive amenities, there are some things to consider. When traveling, the majority of the RV is not accessible with the slides in. Some of the awning space in the middle of the RV is taken up by the dinette slide. Because the RV is so large and heavy it will require at least a 1-ton pickup truck to tow (a dully might be best).


The Keystone Montana 3901RK is a remarkable fifth wheel that epitomizes luxury and functionality. From the innovative rear kitchen design to spacious living areas and well-appointed bathrooms, this RV offers everything you may need for a premium RVing experience.

Keystone’s attention to detail and commitment to customer feedback are evident in the thoughtful features and amenities. Whether you’re looking to stay in this RV full time, or take it to the campground, the Keystone Montana 3901RK is an ideal choice.
