What happens when a manufacturer actually listens to your feedback? You get something like the Brinkley Model Z 3420.

This isn’t just a new floor plan — it’s the smarter, more functional follow-up to the Z 3400.

Brinkley flipped the layout, moved the windows to the camp side, kept the rear patio, and cranked up the storage like they were playing RV Tetris. It’s clear they weren’t just aiming for different — they were aiming for better.

If you want a fifth wheel built for campers who need room to live and features that actually make life easier, the Z 3420 is worth a serious look.

Let’s take a closer look under the hood (well… under the roof).

Josh the RV Nerd tours the Z 3420 and explains how Brinkley listened and leveled up.

What makes the Brinkley Model Z 3420 Unique?

Brinkley Model Z 3420 Rear Patio and Bar

The Z 3420’s rear patio gives you a true outdoor living space — no garage, just room to relax.

The Brinkley Z 3420 isn’t a brand-new invention — it’s a thoughtful remix of their popular 3400 model, rebuilt based on real camper feedback.

The most noticeable change? They flipped the living and kitchen areas to put the windows on the camp side — so you’re not staring at your neighbor’s sewer hose while you drink your morning coffee.

They also kept the rear patio and added a one-touch “weather wall” you can drop down to block wind or rain, giving you a usable three-season hangout space.

A few more things Brinkley got right:

  • 12V fridge in the rear kitchen, accessible while traveling
  • A huge amount of storage — close to 3,000 lbs of cargo capacity
  • A redesigned dining/desk bar setup with built-in power for remote workers or guests
  • Camp-side windows throughout the main living area
  • An optional rear entry with lightweight, skirt-mounted steps that stow inside a lockbox

If you liked the 3400 but wanted a better view, easier storage access, or more airflow — the 3420 fixes those issues without losing the Brinkley feel.

What Are the Interior Features of the Brinkley Model Z 3420?

Inside the Brinkley Z 3420, it’s less “typical fifth wheel” and more “why doesn’t every RV do this?”

The living space has been flipped to put the big windows and seating area on the camp side — so your morning coffee view is the trees, not your neighbor’s sewer hose.

The rear patio and wet bar turn the back of your RV into a great spot to kick back and relax, and with the one-touch “weather wall,” you don’t have to pack it in just because it’s drizzling.

You also get two 18,000 BTU A/C units — one for the main living space and one for the bedroom — both with quiet, variable-speed compressors and built-in heat pumps. Translation: cool in the summer, warm in the fall, and no loud blasts of air every five minutes.

The kitchen is built for day-to day use — with solid surface counters, a huge island with trash storage, and hidden drawers and pantry space that make it feel more like a condo than a camper.

And yes, it’s Brinkley — so you still get soft-close drawers, dovetail construction, under-bed lighting, washer/dryer prep, and all the little touches you didn’t know you needed until now.

Brinkley Z 3420 Key Interior Features:

  • Camp-side living room with large windows
  • Rear patio and wet bar with 12V fridge (accessible while traveling)
  • Two-zone A/C system with quiet variable-speed units and heat pumps
  • Oversized island with solid surface counters and built-in wastebasket
  • Soft-close drawers with dovetail construction
  • Expandable desk/dining bar with hidden power access
  • Hidden storage throughout kitchen, pantry, and bedroom
  • Optional washer/dryer prep in the bedroom closet
  • RV king bed with motion-activated floor lighting
  • Dual-entry bathroom with extra headroom and molded fiberglass shower
  • Large vanity mirror with backlighting
  • No floor vents in main living space or bathroom (aka: less to sweep)

If you’re the kind of camper who appreciates good design and hates wasted space, the Z 3420 might just be your new favorite floor plan.

What’s So Great About the Rear Patio and Wet Bar on the Z 3420?

It’s not just a cool add-on — the Z 3420’s rear patio is one of the most functional and fun features in the whole floor plan.

Instead of wasting the back wall, Brinkley gave you a true three-season hangout space. With solid flooring, full railing, and a one-touch “weather wall” to block wind and rain, you can enjoy the outdoors even when the weather’s not ideal. Set up a couple chairs, cue the sunset, and you’ve got your own back porch on wheels.

Just inside the door is a small wet bar with cabinet space, countertop, and a 12V fridge that stays powered while you travel.

You don’t have to head inside every time you want a drink or snack — just pop open the fridge and keep enjoying the patio.

Let the good times roll!

  • 12V fridge accessible in transit (perfect for road-day snacks)

  • Separate rear entry door from the patio
  • Lightweight, skirt-mounted stairs that slide into a lockbox
  • A real bonus room — not a toy hauler garage pretending to be one

What Are the Exterior Features of the Brinkley Model Z 3420?

The outside of the Z 3420 is built like it’s meant to be used — a lot!

You get a painted aluminum exterior instead of standard fiberglass, which holds up better over time and is easier to repair if something goes sideways.

The heated, enclosed underbelly and radiant barrier insulation help extend your camping season, and the tankless water heater means long showers without the wait.

Brinkley also includes 200W of solar power and 3,000W inverter prep — giving you a head start on off-grid camping or just more flexibility when hookups aren’t available. You don’t have to build your boondocking setup from scratch.

And when it comes to storage, Brinkley didn’t cut corners. The oversized drop-frame pass-through can handle bulky gear like chairs, totes, or tables — and there’s even more room in the rear patio compartments.

Brass PEX plumbing keeps everything tucked cleanly out of the way, so you can actually use the space.

Brinkley Z 3420 Key Exterior Features:

  • Painted aluminum exterior for better durability and repairability
  • Heated and enclosed underbelly with radiant barrier insulation

  • 60,000 BTU on-demand tankless water heater

  • 19′ power awning with dimmable LED lighting
  • Outdoor gas grill quick-connect hookup

How Easy Is the Brinkley Z 3420 to Tow?

Let’s be real — this isn’t a lightweight travel trailer. It’s a big fifth wheel with big features, and that means you’ll need a properly equipped three-quarter-ton truck or heavier to handle it safely.

But Brinkley did their part to make towing feel more stable and secure. From the anti-lock brake system (ABS) to electronic sway control and hill-start assist, this 5th wheel is designed to help you stay in control, even when the road gets a little sketchy.

Towing & Safety Highlights:

  • ABS electric brakes – helps reduce wheel lockup for smoother, safer stops
  • Sway control – adds stability when towing in wind or on rough roads
  • Hill-start assist – keeps the rig from rolling back on inclines
  • Heavy-duty suspension system – for a smoother ride and better handling
  • TPMS-ready tires – compatible with tire pressure monitoring systems
  • Turning point pin box – tighter turns in tighter spots
  • LED hitch & marker lights – better visibility when towing at night or in low light

Towing Tips for the Brinkley Z 3420

With a GVWR of 16,800 lbs and a hitch weight around 2,600 lbs, the Z 3420 is built for three-quarter or one-ton trucks — ideally with a diesel engine and a factory tow package.

You’ll want a fifth wheel hitch rated for the load, and if you’ve got a short bed truck, a sliding hitch can save your rear window in tight turns.

Is the Brinkley Z 3420 a Good Fit for You?

This fifth wheel isn’t for everyone — that’s not a flaw, it’s the feature. Here’s who the Z 3420 is built for, and who might want to look at something a little different.

The Brinkley Z 3420 Is a Good Fit For:

  • Campers who want luxury features without stepping into a massive RV

  • Anyone who loves the idea of a rear patio and wetbar setup
  • RVers who appreciate good storage, thoughtful layouts, and smarter design
  • Towable fifth wheel fans with a truck that can handle serious weight

It Might Not Be the Best Fit If:

  • You don’t have a three-quarter or one-ton truck to tow it
  • You prefer a traditional rear living layout without a patio
  • You’re camping with a large group and need extra sleeping space
  • You’re shopping for a more budget-conscious or beginner-friendly RV
  • You’d rather have a toy hauler garage than an open patio space
