Living Area Features

The living area in the Momentum 414M is designed to stand apart from typical toy hauler designs. Unlike many toy haulers that prioritize the garage at the expense of living space, this model balances both seamlessly.

It features a theater seat directly across from the TV for optimal viewing, and a hide-a-bed sofa to accommodate extra guests. The highlight is the dining area on the campsite side, boasting a massive picture window, enhancing the dining experience with scenic views.

The living area is also carpetless with opposing floor-flush slides, making it easy to clean and maintain.


The garage area is thoughtfully designed with HappiJac power bed lifts that can be used as double queen beds, offering additional sleeping space. The garage also includes a loft area for extra sleeping or storage. The space is well-lit and features several windows, making it airy and bright. The ramp door is designed for all-weather use and doubles as a patio, extending the living space outdoors.

Kitchen Features

The kitchen in the Momentum 414M is great with its U-shaped wraparound design, offering plenty of counter space and storage. It’s positioned so that everything is easily accessible, reducing traffic through the cooking area. This design allows the cook to be part of the social scene while preparing meals.

Key features include a large farm sink with a versatile cover and a side drain for better runoff, along with a 20 cubic foot 12-volt compressor fridge and a large four-burner Insignia oven/stove combo. The kitchen is both practical and stylish, perfect for preparing meals while enjoying the RV lifestyle.

Bathroom Features

The bathroom in the 414M is thoughtfully designed with dual entries, providing convenient access from both the hallway and the bedroom. This feature enhances privacy, especially at night or when guests are present. The bathroom space is surprisingly roomy, accommodating a porcelain foot-flush toilet comfortably.

One standout feature is the step-down shower with a fold-down seat, a design that maximizes headroom, making it comfortable for taller individuals. The shower enclosure is molded fiberglass, ensuring durability and easy maintenance. The dual entries may raise concerns about privacy for some, but they add a layer of convenience and flexibility in accessing the bathroom.

The medicine cabinet and additional storage spaces are cleverly designed to utilize the area efficiently, providing room for toiletries and linens. This setup is especially useful since many RV bathrooms lack sufficient storage.

Bedroom Features

Moving to the bedroom, the Momentum 414M’s centerpiece is a king-size bed, providing plenty of space for a restful night’s sleep. For those who prefer more walk-around space, the option for a queen-size bed is available.

Storage solutions in the bedroom is great with overhead cabinets, bedside stands, and under-bed storage offer ample space for personal belongings. The bedside stands are particularly noteworthy – they are fold-out, meaning they can be tucked away when not needed, maximizing space around the bed.

The bedroom’s design also emphasizes convenience and comfort. Both sides of the bed have household and USB outlets, making it easy to charge devices. Additionally, the bedroom’s decor and ambiance are calm and inviting, ensuring a peaceful environment to unwind after an adventurous day.

Nightstands weren’t added in order to save you space for a larger bed!

Road Mode: Travel Access

In road mode, the Momentum 414M maintains excellent accessibility to essential areas. The bathroom and bedroom are easily accessible without needing to open any slides, making quick stops convenient. The kitchen and refrigerator are partially accessible when the slide is closed, offering enough room to grab snacks or drinks during a journey.
