Our Favorite Large Fifth Wheels
Here is a selection of the biggest fifth wheel campers over 43 feet:
Prime Time Sanibel 3982DBWB
Specs
- Length: 46’2”
- Slide-outs: 5
- Dry Weight: 14,489 pounds
- Cargo Capacity: 2,486 pounds
- Sleeping Capacity: Up to 6
At just over 46 feet, the Sanibel 3982DBWB is one of the longest fifth wheels available. It’s also one of the most innovative. The flexibility of the front bedroom with attached full bath makes it unique, as it can serve as a second bedroom suite, an office, or a bonus lounge space. This room features a queen Murphy bed that converts to a desk, a tri-fold sofa, and a 40-inch television.
The main living space is gorgeous for cooking, dining, and entertaining. What family chef wouldn’t love this kitchen? It features a massive center island with clever features like a flip-up breakfast bar, slide-out dinette, hidden trash can storage, a cutting board, and paper towels. The kitchen doesn’t end there, as you’ll also find a large pantry, double-door fridge, and storage hutch with a coffee bar.
Nearby, a massive sofa provides seating for at least five people. It is across from a deluxe entertainment center with an electric fireplace, a hidden 50” TV, and a premium sound system. Head to the rear for a king bedroom suite with dual vanities and an oversized shower.

Specs
- Length: 44’9”
- Slide-outs: 4
- Dry Weight: 17,090 pounds
- Cargo Capacity: 3,910 pounds
- Sleeping Capacity: Up to 4
The two words that come to mind when you enter the Redwood 412GK are “airy” and “spacious.” Where some long fifth wheels dedicate space to an additional bedroom, this model has one roomy suite with a walk-around king bed, extensive storage wardrobes, and washer/dryer prep. The attached pass through bathroom has the vanities divided on separate walls, giving each person more space for the morning routine.
The central living space flows from a residential-style kitchen with a central island to a rear living room with theater seats and an 80” tri-fold sofa. Whether it’s movie night or game day, you won’t miss a move on the massive 65” TV.
You might notice the weight of this model. That shows you how packed it is with hidden features, from the on-demand water heater to the central vacuum system. Made to withstand temperatures from 0℉ to 110℉, the 412GK is ready for extended-season living. You won’t have to sacrifice comfort, thanks to the bonus 15,000-BTU air conditioner, something I would appreciate in such a large fifth wheel.

Specs
- Length: 44’5”
- Slide-outs: 4
- Dry Weight: 15,455 pounds
- Cargo Capacity: 3,045 pounds
- Sleeping Capacity: Up to 6
While open-concept spaces are great, I sometimes think a slight separation is lovely. The Pinnacle 38FLGS features an upper front living room with seating for at least eight and a 50” TV. This is a cozy gathering spot for entertaining or for hosting guests, or a place to send the family so you can cook in peace.
The rear reveals additional surprises, including a grand bathroom with extensive countertops, dual vanities, and a shower with teak seating. The center of the trailer features a kitchen decked out with residential GE Profile Series appliances, including a 21-cubic-foot refrigerator and a 24-inch range.
As part of Jayco’s luxurious Pinnacle line, the 38FLGS has premium features like a NuVo water filtration and softening system, JBL sound system, and high-efficiency HELIX Cooling System with Whisper Quiet technology.

Forest River Sierra 3800RK
Specs
- Length: 44’1”
- Slide-outs: 4
- Dry Weight: 12,849 pounds
- Cargo Capacity: 2,651 pounds
- Sleeping Capacity: Up to 4
If hidden storage is essential to you, you’ll love the Sierra 3800RK, which offers a massive front walk-in closet. If you’re living in an RV full-time, you know how desirable this space is for storing four seasons of clothes, outdoor gear, and even holiday decorations.
Have you ever seen an RV with a laundry room? I hadn’t until I saw the 3800RK. While many RVs tuck the washer and dryer into a bedroom or bathroom closet, this big 5th wheel has side-by-side units topped with a countertop and storage in an actual laundry room.
As someone who frequently works from the road, I love that this camper has a dedicated desk and breakfast bar seating. You will also find extensive wrap-around counters surrounded by storage cabinets.

Specs
- Length: 44’
- Slide-outs: 3
- Dry Weight: 11,318 pounds
- Cargo Capacity: 2,922 pounds
- Sleeping Capacity: Up to 4
The 44-foot Arctic Wolf 3800DECK uses some of its prime real estate for a desirable amenity: a covered patio. Picture yourself lakeside, enjoying the breeze on your large deck with a ceiling fan, LED lighting, and a propane quick connect. Since it is fenced and has a gate, this is also a nice spot for your dogs to chill.
Despite the square footage dedicated to the deck, the inside doesn’t feel cramped for space. Windows fill the walls, allowing natural light to flood in. The rear living room features a large L-shaped couch and a multi-function desk/table. A hidden pantry is tucked away behind the entertainment center.
You’ll also find exciting features in the front bedroom, like an electric fireplace, wrap-around windows, washer/dryer prep, and a bench seat. The Elemental Protection Package adds additional features for extended-season camping.

For the ultimate family hangout, check out the North Point 382FLRB. The front living room has two tri-fold sofas and a pair of theater seats, allowing you to seat at least eight. This cozy area has a 50” TV and an electric fireplace. Plus, it adds a semi-private space for guests to sleep, and there’s a second 32” TV for viewing from the kitchen or dinette.
The kitchen feels like its own space and features a large island, an extendable roll-top dinette, and GE Profile residential appliances, including a 21-cubic-foot refrigerator. The GE microwave has an air fryer feature, which allows you to enjoy its usefulness without taking an extra appliance on the road.
The 382FLRB’s bathrooms are surprisingly impressive. The primary suite bathroom stretches across the entire rear wall, offering dual vanities, a walk-in shower, and washer/dryer prep. A second half bath is located off the kitchen, providing easy access for guests.

You’ll find a massive central living space on the main floor with a spacious kitchen and dining area. Nearby, a combo bathroom-laundry room is an amazing bonus space with a side-by-side washer and dryer topped by a flip-up countertop for folding clothes.

Above it, you’ll find a hidden loft with room for children to sleep, or a great storage space for extra gear.
The rear kitchen features upper cabinets that stretch to the ceiling, with solid surface countertops. Nearby, the living room has a residential touch, with a wood accent wall topped by a large TV and an electric fireplace. Thanks to the theater seating, hide-a-bed sofa, freestanding dining table, and desk, a big group can gather here.
Some optional features take this large fifth wheel to the next level. Add a third AC for easier climate control if you’re camping in warm places. For off-grid power, add a second solar panel and an LP generator. Slide-out awning toppers add extra protection you’ll appreciate.
