The Brinkley Model G 4150 and Model G 4155 are nearly identical luxury toy-hauler fifth wheels — sharing the same chassis, garage, living area, kitchen, and bedroom layout. The only real difference is the front section. The G 4150 features a dedicated front office, while the G 4155 replaces that space with a front bunkroom for added sleeping capacity.
Everything else — from the triple A/C system and GE Profile appliances to the 740 watts of factory solar and standard disc brakes, is exactly the same.
This comparison less is about specs and more about lifestyle! So the big question is, are you building a mobile office or a family basecamp?

Why This Office Changes RV Life
If you’ve ever tried to work on the road, you know that most RV “offices” are an afterthought— tiny dinette corners, hallway desks, or bunk conversions with no privacy. The Brinkley Model G 4150 changes that entirely.
This is not a workspace squeezed into a living area where chaos happens all around you; it’s a true front office suite, complete with a solid door, windows, and intentional design that rivals many home offices!
Private, forward office behind a door—quiet, focused, and separate from the living room chaos.
Height-adjustable work surface (great sit-height range; not a true stand-up height), sized around a picture window with blackout/day shades.
Real office storage: dual legal-size hanging-file drawers, drawer organizers, flip-top console with strong magnets, integrated trash, and plenty of outlets.
Comfort built-in: dedicated supply/return vents for heating & cooling right in the office.
For entrepreneurs, digital nomads, and work-from-anywhere couples, this layout is a game-changer.
Living Room & Entertainment
The Brinkley Model G 4150 (and its twin, the Model G 4155) carries forward the lounge layout that made the G-series famous, only now, it’s been re-oriented north to south, meaning the entertainment center and TV now face toward the rear of the fifth wheel. It’s a small change that makes a big difference in how the entire living space flows.
By flipping the orientation, Brinkley optimized both the sightlines and the sense of openness, giving you a more residential feel from every angle.
At the heart of the living area is Brinkley’s signature quad “party recliner” setup. The two end seats come equipped with heat and massage functions, creating the perfect spot to unwind after a long drive or day of working in the front office. The middle recliners operate manually and are ideal for lounging.
Panoramic windows plus over-slide storage (tall ceiling makes room for cabinets).
Everybody gets the TV: sightlines from the entry, island, and seating are all clean.
This living area strikes a perfect balance between luxurious comfort and everyday function, proving that a toy hauler can double as both a professional workspace and a high-end entertainment suite.
Kitchen and Island Storage
The kitchen in the Brinkley Model G 4150 (and Model G 4155) proves that you can have both luxury residential comfort and RV practicality.
From its premium GE Profile appliance suite to its soft-close cabinetry and smartly hidden features, this kitchen feels more like a modern home than a mobile toy hauler.
The sink base is prepped for a dishwasher, and the dovetail drawers, a hallmark of Brinkley’s high-end construction, slide silently shut with soft-close guides.
The island is a true multitasking hub. It includes a built-in paper-towel cradle, a removable cutting board insert, and deep utensil drawers for oversized tongs and spatulas.
3,000W pure-sine inverter + 200Ah lithium + ~740W roof solar (standard) keeps the fridge humming on travel days.
GE Profile appliance suite with a shock-rated 110V residential fridge (Energy Star).
Between the spacious prep surfaces, energy-efficient power system, and storage design, the kitchen in both the Model G 4150/4155 doesn’t just keep up with residential standards, it sets the standard. It’s the kind of layout that makes cooking and entertaining, on the road, an elevated experience.
Bedroom & Primary Bath
The Brinkley Model G 4150 and 4155 share the same rear bedroom and bath layout, both designed for full-time comfort and relaxation.
Whether you choose the front-office floorplan (4150) or the front-bunk configuration (4155), the sleeping quarters are built to deliver residential-level rest after a long day of travel, work, or play.
The king bed slide includes a factory-installed, pillow-top mattress that’s actually comfortable — and not the thin foam pad you’ll find in most fifth wheels.
The platform is supported by strong gas struts, so lifting it for under-bed storage doesn’t feel like an upper-body workout. It’s smooth, stable, and holds itself open as you organize gear or access stored items.
The motion-sensing night lighting along the floor baseboards gives you just enough glow to move safely at night without waking your partner — a subtle but highly functional feature that RVers quickly learn to love.
Seven-drawer dresser, closets with power for stick-vac charging, motion-sense night lighting at the floor.
For families or travelers who need extra sleeping capacity, the Brinkley Model G 4155 swaps the front office found in the 4150 for a thoughtfully designed front bunkroom. This space includes multiple bunks, deep wardrobe storage, and solid privacy doors — turning the front cap into a quiet retreat for kids, grandkids, or guests.
Bathroom
Stepping into the primary bathroom, Brinkley continues its tradition of upscale functionality. A solid-surface vanity with plenty of counter space gives the bathroom a true spa-style aesthetic, paired with a high-capacity XL vent fan to keep the air fresh and moisture-free.
The one-piece molded fiberglass shower feels open and watertight.
Between the king-suite comfort, intelligent lighting, and easy-access service design, the bedroom and bath areas in both the 4150 and 4155 make this coach feel like a luxury apartment on wheels.
Garage, Half-Bath, & Patio
Step through the sliding glass door and you enter what might be the most versatile part of the Brinkley Model G 4150 and 4155 — the 11-foot rear garage.
Don’t think of it as just a cargo bay; this is a true multi-purpose flex room. It can be a second bedroom, a private office, a teen lounge, a home gym, or a transport zone for kayaks, e-bikes, golf carts, or smaller side-by-sides.
Brinkley intentionally designed this space for usability over raw size, so while it’s not built for the giant four-seat SxS rigs, it’s perfect for modern adventurers who want livability without losing garage utility.
Collapsible half bath in the garage: fold it when you need the length; use it for daytime privacy.
Three-season wall (updated latch top & bottom) and Zero-G ramp that feels like an SUV hatch.
Chassis, Suspension & Brakes
Underneath all the high-end living space, office innovation, and luxury finishes, the Brinkley Model G 4150 and 4155 are built on a foundation engineered for travel performance. Brinkley didn’t cut corners here — they overbuilt it.
From the welded steel frame to the advanced braking and independent suspension system, this chassis was designed to handle heavy loads, long hauls, and rough roads with the confidence and composure of a premium automotive platform.
At the front, Brinkley’s frame is engineered for Gen-Y pin box compatibility straight from the factory. Unlike many RVs that retrofit aftermarket torsion boxes onto frames that were never designed for them, Brinkley integrated the necessary reinforcement directly into the chassis design. This means better stress distribution, less frame flex, and a more stable towing experience overall
For those who demand the smoothest ride possible, Brinkley offers the MORryde Independent Suspension (IS) system — a premium upgrade often described by owners as “a no-going-back feature.”
Underneath, H-rated Uniroyal tires deliver serious load-carrying strength, paired with a heavy-duty Dexter equalization system that smooths out road vibration and minimizes stress across the axles.
Together, these chassis and suspension features make the Brinkley Model G 4150 and 4155 more than just beautiful RVs — they’re robust, road-ready machines built for long-term use.
Exterior Storage & Smart Details
Segmented pass-through with adjustable partitions and three MORryde slide trays (2 curbside, 1 roadside).
Firefly multiplex with more diagnostics and multi-zone audio (living/outside/garage).
Programable keyless deadbolt, aircraft-style latches, brush-cleanable step backs, and a baggage-door safety interlock that prevents crushing during auto-level.
Onboard 135 PSI air compressor and dual 30-gal fuel station (separate tanks; you can back-fill generator tank for 60 gal total).
Roof upgrade: new fiberglass-polypropylene membrane over a gasketed sealing system for tougher branch scuffs and lower maintenance (still do your checks!).

Signature gold accent (Porsche-code-inspired) turns heads—dramatic without being loud.
“Metallic” package adds a crisp silver accent.
Who Should Choose Which Version?
Front-Office Model G: Remote workers, creators, entrepreneurs, or anyone who needs a door-shut workspace that feels like a real office.
Model G 4155 (Front Bunk): Families who want fixed bunks and still love the G-series living room, kitchen, and garage flexibility.
Brinkley G 4150 + G 4155 | FAQ
Is the front desk a true standing desk?
It’s height-adjustable within a generous seated range. There’s room to stand and work in the office, but the desk itself doesn’t rise to full stand-height.
Can I run the residential fridge on travel days?
Yes. The 3,000W inverter, 200Ah lithium, ~740W solar, and DC-to-DC charger are designed to support the 110V fridge while rolling. Generator backup is on board.
What’s the garage length and who is it for?
Approx. 11 feet—ideal for e-bikes, kayaks, compact toys, or a second lounge/bedroom. For giant four-seat side-by-sides, look at Brinkley’s longer garages.
Are disc brakes standard?
Yes—disc brakes are now standard on Model G. You can also option MORryde Independent Suspension for a major ride/handling upgrade.
How is the A/C configured?
Three mini-ducted zones (office/bed/bath; living; garage) with heat pumps, plus a propane furnace and fireplace—quieter, faster, and more efficient comfort.
What’s different about the roof?
A fiberglass-polypropylene membrane and gasketed sealing approach for tougher scuff resistance and reduced upkeep (still inspect seasonally).
Office or front bunk—what changes besides that room?
Nearly everything else—living, kitchen, garage, systems—remains the same. The G 4155 simply trades the front office for a front bunkroom.
Whether you work from home/ on the road or want bunk beds to keep the kids closer, you can have either/or without giving up the Model G luxury!
Brinkley didn’t just wedge a desk into a corner; they built a legitimate front office with storage, privacy, and HVAC.
Pair that with the G-series lounge, residential kitchen kit, robust factory power package, and road-ready braking/suspension, and you have one of the most compelling “live, work, and play” toy-hauler fifth wheels on the market!
