Axiom Imperium RVs For Sale
Axiom Imperium luxury fifth wheels for sale at Motor Home Specialist, the #1 Volume Selling Motor Home Dealer in the World and the #1 Axiom RV dealer in the country.
The Imperium is Axiom's flagship luxury fifth wheel, designed by RV industry veterans for full-time RV owners and traveling families who want a residential-feeling living space, oversized seating capacity for entertaining, and innovative features like the I3800's self-deploying side patio off the bedroom. Couples shopping the I2900 as a more manageable footprint, and entertainers or larger families looking at the I3800 or I3900 as a full-time residence with dual patios and 1.5 baths, will find the Imperium hits a different point in the luxury fifth wheel market than typical builds in this segment.
Every Imperium is built around three standard equipment packages: the Lux Package, the Essential Package, and the AX Comfort Package, which together cover suspension, structural, electrical, climate, kitchen, and bath features.
The Lux Package handles the chassis and structural foundation. It includes the Curt Touring Coil suspension system, low-alloy steel construction (rated 72% stronger than standard fifth wheel framing), 17.5-inch rims with H-rated tires, the Axiom ClearSpan roofing system, deluxe graphics with marine-grade fiberglass exterior, the Solid Step triple entry step, the main glass entry door with assist grab handle, and the Pathfinder lighting system with integrated turn signals. Construction is engineered to handle full-time use and long-distance towing without the chassis flex that plagues some lighter-built fifth wheels.
The Essential Package adds the Lippert 6-point hydraulic leveling system, the Perfect Air 9000K triple mini-split climate system, the PowerPro control panel, the extended-latch entry door lock system, battery and solar disconnects, a 200-watt solar panel paired with a 2,000-watt inverter, and the patent-pending AX Flex Ottoman.
The AX Comfort Package adds solid-surface kitchen countertops, the king-size mattress with bed tilt system, G20-tinted frameless windows, StowMax storage, Starlink prep, hardwood cabinet doors with slow-close hidden hinges, a 22-cubic-foot 110V residential refrigerator, the Ultimate Kitchen Sink, a 65-inch LED HD Smart living room TV, a Fogotti on-demand water heater, and electric gate valves on all holding tanks.
The I2900 measures 33 feet 11 inches long, 13 feet 5 inches tall, and 102 inches wide, with a dry weight of 15,990 pounds, a pin weight of 2,300 pounds, and an 18,500-pound GVWR. It uses an exclusive U-shape living area that seats up to 18 people, making it the entertaining-focused floor plan in the lineup. The bedroom uses dual opposing slides to create an expansive king-bed suite, and the rear kitchen layout maximizes counter space and storage. A patent-pending rear-mounted generator option opens up the largest pass-through storage in its class. The I2900 is built for travelers who want maximum interior space in a length they can park at typical state parks and longer-stay campgrounds without booking the largest pull-through sites.
The I3800 measures 41 feet 11 inches long, 13 feet 5 inches tall, and 102 inches wide, with a dry weight of 18,980 pounds, a pin weight of 3,250 pounds, and a 24,000-pound GVWR. It includes two industry-first features: a self-deploying side patio off the bedroom that opens in seconds, and a rear patio with a built-in bar area. The U-shape living seating handles up to 12 guests, the front bathroom uses a massive front window for natural light, and the floor plan includes a 1.5-bath layout that adds a powder bath for families and entertainers. The rear kitchen pairs extensive cabinet storage with a large countertop area.
The I3900 measures 42 feet 11 inches long, 13 feet 5 inches tall, and 102 inches wide, with a 24,000-pound GVWR. It's the longest floor plan in the Imperium lineup. Dry weight is to be confirmed, and pin weight figures will follow once final production numbers are released by Axiom.

Optional equipment available across the Imperium lineup includes a front pass-through pull-out tray, a front pass-through easy-access ramp door, a second 190-watt solar panel, slide toppers, the AX Camera Package (rear and side cameras), dual-pane windows, a Splendid washer/dryer, a Furrion dishwasher, a 6 kW LP generator, the Midnight Exterior Package, the AX-EZ-Swing, and the DeeMaxx hydraulic double or triple axle disc brake system.

Axiom Imperium FAQs
What is the Axiom Imperium?
The Axiom Imperium is a luxury fifth wheel designed for full-time RV living, families, and entertainers. It includes residential interior finishes, oversized U-shape living seating that handles up to 18 people on the I2900, a king-bed master suite, the Lux/Essential/AX Comfort standard packages, and innovative options like the I3800's self-deploying side patio off the bedroom and rear patio with bar area.
Is the Axiom Imperium a fifth wheel?
Yes, the Imperium is a fifth wheel, towed by a pickup truck using a fifth wheel hitch installed in the truck bed. It's not a motorhome and doesn't have its own engine. A pickup truck rated to handle the Imperium's pin weight and GVWR is required.
What truck do I need to tow an Axiom Imperium?
Truck requirements depend on floor plan. The I2900 has an 18,500-pound GVWR with a 2,300-pound pin weight, which most modern three-quarter-ton or one-ton diesel pickups can handle when properly equipped with a fifth wheel hitch. The I3800 and I3900 both have a 24,000-pound GVWR, with a 3,250-pound pin weight on the I3800. These larger floor plans require a one-ton (or larger) heavy-duty diesel pickup with the appropriate fifth wheel hitch rating. Always verify your specific truck's GCWR, payload capacity, and rear axle weight rating against the loaded fifth wheel weight before towing.
What floor plans does the Axiom Imperium come in?
Motor Home Specialist offers the Axiom Imperium in three floor plans: the I2900, the I3900, and the I3800. The I2900 is the shortest at 33 feet 11 inches with the 18-person U-shape seating and king-bed suite. The I3800 is 41 feet 11 inches with dual patios and 1.5 baths. The I3900 is the longest at 42 feet 11 inches.
How much does the Axiom Imperium weigh?
The I2900 has a dry weight of 15,990 pounds, a pin weight of 2,300 pounds, and an 18,500-pound GVWR. The I3800 has a dry weight of 18,980 pounds, a pin weight of 3,250 pounds, and a 24,000-pound GVWR. The I3900 has a 24,000-pound GVWR with dry weight to be confirmed. All three floor plans are 13 feet 5 inches tall and 102 inches wide.
What is the difference between the Imperium I2900, I3800, and I3900?
The I2900 is the shorter footprint floor plan at 33 feet 11 inches, with rear-kitchen layout, U-shape seating that handles 18 people, and a lower GVWR (18,500 pounds) for buyers who want a fifth wheel a typical heavy-duty pickup can tow. The I3800 is 41 feet 11 inches and adds the dual-patio configuration (self-deploying side patio off the bedroom and rear patio with bar area) along with a 1.5-bath layout. The I3900 is the longest at 42 feet 11 inches with the largest interior square footage. Floor plans, finish packages, and feature differences vary, and your salesperson can walk through the specific differences.
Does the Axiom Imperium have a king bed?
Yes, every Imperium comes standard with a king-size mattress and the AX bed tilt system, which lifts the mattress for easier under-bed storage access. On the I2900, dual opposing slides expand the bedroom into a full king-bed suite. The bedroom also includes hardwood cabinet doors with slow-close hidden hinges and the StowMax storage system.
Does the Axiom Imperium come with solar?
Yes, every Imperium comes standard with a 200-watt solar panel paired with a 2,000-watt inverter, plus battery and solar disconnects, all part of the Essential Package. A second 190-watt solar panel is available as an option for buyers who want additional off-grid range. A 6 kW LP generator is also available as an option.
What is the kitchen like in the Axiom Imperium?
The Imperium kitchen pairs solid-surface countertops with the Ultimate Kitchen Sink, a 22-cubic-foot 110V residential refrigerator, hardwood cabinet doors with slow-close hidden hinges, and the Fogotti on-demand water heater. A Furrion dishwasher is available as an option. The I2900 and I3800 both use rear-kitchen layouts that maximize counter space and storage.
What is the I3800's self-deploying side patio?
The I3800 includes a self-deploying side patio off the bedroom that extends from the body of the fifth wheel at the touch of a button, creating a private outdoor retreat in seconds. The I3800 also includes a rear patio with a built-in bar area for entertaining. Axiom describes this as an industry-first feature.
