Living: More Room, More Seating, Comfort Beyond Expectation


Where do we even begin? When you step inside the Imperium i2900, you’ll feel like you’ve entered a luxury lounge. Axiom engineered the interior around space, seating, and smart design, creating a living area that feels more like a custom home theater than an RV.

Expansive Slides & Ceilings

Monster-Tall Slideouts: The Imperium features slides over 8 feet tall, some of the tallest in the industry, which instantly make the living space feel open and airy.

Wide-Body Frame: Extra width in the chassis creates deeper opposing slides, opening the floorplan and allowing for seating and dining without feeling cramped.

Windows, Views, and Shades

Massive Window Coverage: Nearly every wall is covered with oversized windows for panoramic campground views.

SquareFlow Windows with Integrated Shades: Lower windows feature integrated day/night shades, while upper windows use MSI power shades that can be controlled via remote — no need for a ladder to pull blinds down.

Smart Control & Voice Integration

The Imperium’s interior is tied together with a smart command system. Owners can control lighting, climate, and other systems via:

  • Physical wall panels
  • Bluetooth app integration
  • Voice commands

Entertainment Designed for Real Living

65-inch Smart TV perfectly positioned for direct viewing from the recliners or sofas.

JBL Rolling Sound System: Instead of a fixed tinny RV speaker, the Imperium includes a portable, wheeled JBL sound system that can be rolled outside for tailgating or to the beach.

Residential Lighting Touches: The beam-style lights aren’t just practical — they give the space a modern, high-end aesthetic that feels like a custom living room.

The Imperium’s interior isn’t just big — it’s designed to host, relax, and live in long-term. Whether you’re a couple who wants a true residential space or a family that needs seating for a crowd, this fifth wheel redefines luxury RV living.

Kitchen: Grand & Gourmet


The Axiom Imperium i2900 kitchen feels like it belongs in a high-end home, not just a fifth wheel. Axiom didn’t waste any space — every cabinet, drawer, and surface is purposeful.

Factory-standard dishwasher, and full gas/electric cooking setup. These aren’t RV “lite” appliances — they’re designed for real use.

Countertops & Surfaces: All surfaces are solid surface — no shortcuts here. Even the bathroom carries this theme, which isn’t always the case with other luxury fifth wheels.

Flexible Dining: The telescopic dining table can raise to a traditional table, drop down to coffee-table height, or be removed altogether and taken outside through the wide 30” entry door. Matching stools store neatly and stay secure in transit.

Entertainment Integration: Because of the open-concept rear-kitchen layout, the 65-inch smart TV remains visible to everyone, even while preparing meals.

This kitchen isn’t an afterthought. It’s a full residential space with clever RV-specific touches, blending form, function, and wow-factor.

The Bathroom: Spa-Like Height & Smarter Design


Most RV bathrooms feel cramped. Not here. Thanks to Axiom’s roofline and mini-split HVAC, the bathroom ceiling is taller than nearly any fifth wheel on the market.

Oversized Shower: A one-piece spa-style shower with a rainfall head offers real elbow room. Even at over 6 feet tall, you won’t need to crouch.

Leak Prevention: Instead of cutting skylights or AC vents into the roof above the bathroom, Axiom runs side-mounted ventilation, leaving the roof membrane untouched and dramatically reducing leak risk.

Practicality: A full porcelain flush toilet with ample legroom keeps things comfortable. Axiom even thought to keep wall space open for towel hooks or additional storage customization.

Materials & Storage: Countertops are still solid surface in the bathroom, and storage is better than most luxury RVs. Expect deep drawers that span the hallway and linen cabinetry for towels and toiletries.

The Imperium bathroom isn’t just bigger, it’s smarter. Fewer leak points, taller ceilings, and thoughtful storage make it feel residential, not “RV standard.”

The Bedroom: Diesel Pusher Luxury in a Fifth Wheel


Step into the Imperium’s bedroom and you’ll immediately notice the difference, it feels more like a diesel pusher motorhome than a towable.

Front Windshield View: The largest front windshield in the industry provides panoramic morning light or stargazing at night. Privacy shades close it off completely when needed.

Laundry Ready: The Imperium offers side-by-side washer/dryer prep in its own dedicated closet area — perfect for extended stays.

Opposing Slides: Both sides of the bedroom slide out, creating an enormous amount of floor space. You won’t feel boxed in here.

Power-Incline Bed: The king bed sits on a power incline system, allowing you to adjust for lounging, sleeping, or creating extra walkaround room.

Wardrobe & Storage: What first looks like less closet space quickly reveals itself to be extensive. Full-depth drawers span the hallway, plus overhead and side cabinetry give you more storage than many competitors.

With its massive slides, power bed, and windshield, the Imperium’s bedroom is a master suite designed for full-time living.

Construction: Stronger By Design


Most luxury fifth-wheels run aluminum frames. Axiom takes a different path with steel-structured, vacuum-laminated walls that integrate a low-alloy, corrosion-resistant steel skeleton and dual composite layers. The result is reportedly ~72% stronger than traditional aluminum structures, engineered to track truer, resist torsion, and stay tight over time.

On the outside, the Imperium uses an upgraded, thicker, automotive-inspired fiberglass skin that presents like full-body paint (mirror-gloss appearance) without the weight and upkeep of typical rolled glass.

Climate & Roof: Quiet, Efficient, and Leak-Resistant

The Imperium swaps roof-mounted ACs for multi-zone mini-split HVAC. That brings:

  • Quieter operation (comfort you can hear, or rather, not hear).
  • Lower energy consumption (often cited around ~50% less vs rooftop units).
  • A cleaner roofline—no big AC cutouts, skylights, or extra vents.

Fewer roof penetrations = fewer leak paths. With so little on the roof, Axiom pushes ceiling height to a level fifth-wheel owners rarely see —taller slides, more headroom, and a true residential feel.

Ride, Handling, & Safety

Touring Coil Spring Suspension helps absorb broken pavement and campground washboards, keeping cabinets—and your nerves—intact.

CURT Helix™ Pin Box (the “matching Helix/Helux” you may see referenced) complements the suspension for better chucking control.

Antilock Braking + Electronic Anti-Sway adds a modern safety net when crosswinds, traffic turbulence, or emergency maneuvers show up.

Axiom Imperium i2900 (Q&A)


Q1: What’s different about Axiom’s wall construction?
A: Instead of aluminum, Axiom uses steel-structured, laminated sidewalls with dual composite layers (dual Azdel-style). It’s reportedly ~72% stronger and uses low-alloy, corrosion-resistant steel to better resist flex and long-term fatigue.

Q2: Why mini-split HVAC in an RV?
A: Mini-splits are quieter and more energy-efficient than rooftop units, and because they’re not roof-mounted, the Imperium’s roof has far fewer penetrations, which reduces potential leaks and enables significantly taller ceilings.

Q3: Does the Imperium really have more seating than most RVs?
A: Yes. It offers extensive seating, including multiple full reclining theater seats, more than almost any RV on the market.

Q4: How does it tow and ride?
A: The Touring coil spring suspension and CURT Helix™ pin box help reduce chucking and bounce. Antilock braking with electronic anti-sway adds confidence in variable conditions.

Q5: Will I lose front storage if I add a generator?
A: No. The optional underbelly (basement) LP generator preserves the Imperium’s front storage capacity, which is among the largest you’ll find.

Q6: What’s the deal with the lighting turning amber on the road?
A: The color-programmable beltline LEDs automatically switch to DOT-approved amber when you plug into your tow vehicle. With Axiom’s patent-pending system, the entire sidewall becomes a turn signal for dramatically improved visibility.

Q7: Who is Axiom RV, and can I trust a new brand?
A: Axiom’s leaders are industry veterans (Heartland RV, Cruiser RV) with decades of experience. Their goal is to fix long-standing shortcomings with smarter engineering and better serviceability. As with any new brand, the real-world test is time, but the pedigree and ideas are strong.

The Axiom Imperium i2900 isn’t just another luxury fifth wheel, it’s a bold statement in the RV industry. From its steel-structured walls and energy-efficient mini-splits to its massive seating, patent-pending lighting, and innovative storage solutions, every detail reflects Axiom’s mission to build smarter and deliver more of what RVers actually want.

Cutting-edge engineering, residential-level comfort, and the functional living — the Imperium i2900 proves that it was not built just to compete, it was built to lead, it was built for more.
