2025 Grand Design Momentum G-Class 5th wheel floorplans


The 2025 Momentum G Class fifth wheel comes with five different layouts to pick from. The 320G comes with an 11’ garage, and the 350G has a 14’ 6” garage. Both packages come with identical floorplan layouts. Both include two entrances with aluminum steps to the garage and the main living area. Walking into the garage area, you will see tie-downs mounted to the floor to ensure your toys are not going anywhere during transit. On the opposite sides of each garage, you will find two Happy Jac rollover sofas with a tabletop. These sofas can be used as an eating space for meals or can be converted into a comfortable bed. While you are in the garage, you will notice overhead storage for belongings as well as a half bathroom that is sectioned off from the rest of the camper. Stepping into the main living area, you will have theater seating that lives in a slide out to your left, directly across from your entertainment center, with a large LED TV and fireplace. Grand Design put the kitchen appliances in another slide-out that was built into the same room. There are a lot of counters and a big farm-style sink in the kitchen. There will be a 12-cubic-foot fridge, microwave, and oven in each room. You can get to the full bathroom from the hallway that leads to the master bedroom. It has a sunken tub shower and a window. In this bathroom, there is a lot of room to get ready in the morning and do your business. You can store your clothes in the closet and on the 60-by-80-inch queen bed in the master bedroom. At over 24 feet long, the 355G has the largest possible garage room of all the models. In the front of the 355G, there is a big bedroom that comes with either a queen bed or a king bed. A big closet and chest of drawers are hidden in a small slide-out on the wall. On either side of the bed are built-in tables with USB charging ports. There are also cabinets above the bed for extra storage. The master bathroom is on your right as you leave the bedroom. It has a big sunken tub/shower and a linen closet on the far wall. The sink and medicine cabinets are on the other side of the ceramic toilet. The kitchen area has a small slide-out that has a roll-out couch and cabinets above it. You can get to it from the bathroom. Then there is a big L-shaped counter with a stainless steel sink, a microwave placed on the cabinet, and a stovetop and oven with three burners. Around the cooking area, there are a lot of overhead cabinets that can be used for storage. Moving toward the garage, there is a dinette with a couch that can be used as storage or turned into a bed, as well as two Euro-style chairs that can be adjusted to fit different people. There are two roll-over chairs and a table for meals in the back, and there is also an available top bed that can be raised or lowered to make more room for sleeping. The 325G's layout is very similar to that of the 355G. The only difference is that the dinette is gone and the floor room is bigger. Also, the garage can only hold vehicles that are 15 feet long. The 415G is the last floor plan, and it comes with a 14-foot car. The bedroom in the front has a queen bed and both ceiling drawers and cabinets and drawers that slide on to the floor. The master bathroom can be reached from either the bedroom or the hallway. As you go downstairs into the living room, you'll see a nice set of theater seats on the slide-out. There are also two other sets of theater seats in the living room, so there are a total of six seats. Your kitchen is on the other wall and has a big L-shaped island and lots of storage cabinets. As you walk into the garage, there is a cool bunk bed area above you and a small bathroom that you can use. It also comes with washer and dryer prep. While you're out in the woods, the Momentum G Class line has all the comforts and high-end features you could want.
