Dynamax RVs For Sale
Dynamax RVs for sale at Motor Home Specialist, the #1 Volume Selling Motor Home Dealer in the World and the #1 Dynamax RV dealer in the country. We stock one of the largest selections of new and used Dynamax motorhomes anywhere, covering the full lineup of Super C diesel and Class C diesel products. Every new Dynamax is priced well below MSRP with industry-leading discounts.
Dynamax RV is a Forest River Inc. company based in Elkhart, Indiana. The brand is built around commercial-grade chassis platforms, Class A diesel pusher-level amenities, and a luxury Super C build philosophy that stands apart from volume-tier manufacturers. Most Class C and Super C products are built to RV-industry minimum chassis specs. Dynamax uses Freightliner M2, Cascadia, Ram 5500, and Ford F-600 platforms instead. The Super C lineup adds air ride suspension, full air brakes, and automatic 4-point hydraulic leveling. These are real medium-duty truck credentials, and buyers downsizing from a 40-foot Class A diesel pusher notice the difference. Every Dynamax comes with custom full-body paint, hardwood Shaker-style cabinetry, residential-grade appliances, automatic leveling jacks, and the all-aluminum no-wood construction that defines the brand.
In the luxury Class C and Super C diesel market, Dynamax sits between volume-tier manufacturers (Thor, Forest River's mainstream Class C lines, Coachmen, Winnebago) and the custom-build ultra-luxury motorcoach segment. The typical Dynamax buyer is often stepping down from a 40-foot diesel pusher. They want the Cummins L9 or Detroit DD16 powertrain, Aqua-Hot or Oasis hydronic heating, and a residential refrigerator and king bed, all in a Super C footprint with a familiar truck-cab driving feel. The Isata family covers the smaller 4x4 luxury Class C segment for off-pavement adventure travel.
Dynamax Super C Diesel Motorhomes
The Super C diesel lineup is the heart of the brand. It includes five products on Freightliner medium-duty and heavy-duty truck chassis, each with its own powertrain and price tier. All five share Dynamax's signature features: air ride suspension, full air brakes, automatic 4-point hydraulic leveling, custom full-body paint, hardwood Shaker-style cabinetry, residential appliances, and luxury vinyl tile flooring throughout.
The Dynamax Grand Sport sits at the very top of the Super C lineup. It's built on the Freightliner Cascadia 126 tandem twin-screw chassis with the Detroit DD16 15.6L diesel, rated at 600 horsepower and 1,850 lb-ft of torque. The numbers put it in true heavy-duty motorcoach territory: an 80,000-pound GCWR, a 32,000-pound ball hitch (or 40,000-pound pintle), three rooftop air conditioners, three lithium house batteries, 800 watts of standard solar, the Oasis hydronic heat system, and a single 45CB dual-bath floor plan.
The Dynamax DX3 is the flagship Super C diesel on the Cummins L9. It rides on the Freightliner M2 106 Plus chassis with the L9 360HP/1,150 lb-ft turbo diesel and Airliner 21,000-pound rear air suspension. It comes in five floor plans (32KD, 34KD, 37BD, 37RB, 37TS) with a 20,000-pound trailer hitch. The DX3 fits stacker-trailer haulers, race team owners, and full-time RV buyers who want commercial-grade chassis parts with luxury interior finishes. The 37BD is the rare Super C bunk model.
The Dynamax Dynaquest XL is the luxury Super C on the Freightliner M2 112 PLUS chassis. Its Cummins L9 steps up to 450HP and 1,250 lb-ft of torque, the same L9 powertrain used in Class A diesel pusher flagships like the Tiffin Phaeton. It offers five floor plans (3200KD, 3400KD, 3700BD, 3700RB, 3801TS), a 20,000-pound hitch, and Aqua-Hot 450D hydronic heating. This is the coach for buyers downsizing from a 40-foot Class A diesel pusher who want the L9 in a Super C footprint.
The Dynamax Europa S is the touring-focused Super C on the Freightliner S2RV Plus chassis with the Cummins B 6.7L turbo diesel (360HP/800 lb-ft). Its lower cockpit design allows a longer floor plan and a roomier cab-over bunk. The single 37CA floor plan has a rear full bath, front half bath, fireplace, king bed with Tilt-a-Bed mechanism, and a 50-by-95-inch cab-over bunk big enough for everyday adult sleeping.
The Dynamax Europa is the more accessible Super C in the lineup. It's built on the Freightliner M2 106B Plus chassis with the Cummins B 6.7L diesel, plus the brand's signature air ride and full air brakes. It comes in three floor plans (31SS, 32KD, 34SS) with 15,000-pound towing and automatic 4-point leveling. Want more sleeping capacity? Add the optional extended fiberglass front cap with a cab-over bunk.
Dynamax Class C Diesel Motorhomes (Isata Family)
The Class C diesel lineup is built around the Isata family: three products on three chassis platforms, from compact Sprinter-based to full 4x4 luxury Class C and Super C. The Isata family is for buyers who want Dynamax build quality and luxury interiors in a smaller footprint, often with 4x4 capability for adventure travel.
The Dynamax Isata 6 is the 4x4 Super C diesel on the Ford F-600 XLT chassis with factory 4-wheel drive and the 6.7L Power Stroke V8 turbo diesel (330HP/950 lb-ft). It offers two floor plans (30FW and 31KS), the DynaRide+ suspension package with Bilstein shocks and MORryde RSX rear shear springs, a 15,000-pound hitch, and a 50-by-79-inch cab-over bunk. The Isata 6 is for buyers who want Dynamax fit and finish in a Super C they can take onto forest service roads and dispersed camping spots.
The Dynamax Isata 5 is the 4x4 luxury Class C diesel on the Ram 5500 chassis with factory 4-wheel drive and the Cummins 6.7L I6 turbo diesel (360HP/800 lb-ft). It comes in two standard floor plans (28SS, 30FW) plus Extreme Package variants (28SSEX, 30FWEX). The Extreme Package adds Liquid Springs smart suspension, a 4-inch rear / 2-inch front lift, super-single rear wheels, and 40-inch tires for real overland capability. With a 10,000-pound hitch and the Cummins 6.7L diesel, the Isata 5 sits above typical luxury Class C products in adventure-tier territory.
The Dynamax Isata 3 is the compact Sprinter-based Class C diesel and the smallest, most maneuverable Dynamax. It's for buyers who want Dynamax build quality and luxury interiors in a Sprinter footprint that drives like a smaller vehicle and fits tighter campsites than the Isata 5 or Isata 6.
What Defines Dynamax Construction and Build Philosophy
Every Dynamax pairs a commercial-grade chassis with all-aluminum, no-wood body construction. Sidewalls are 2-inch aluminum-framed laminated panels with high-density block foam insulation. The floor uses an aluminum frame with a composite flooring substrate. The roof trusses are aluminum, under a crowned one-piece molded fiberglass roof. The exterior is composite fiberglass with no exterior wood anywhere. That approach holds up long-term in conditions where wood-framed Class C and Super C products can develop structural fatigue.
Every Dynamax also comes standard with custom full-body paint in a premium cut-and-buffed finish, where volume-tier competitors use partial paint or vinyl graphics. You also get front-end Diamond Shield paint protection, hardwood Shaker-style cabinetry with full-extension soft-close drawer guides and hidden hinges, luxury vinyl tile flooring throughout (heated porcelain tile on the Grand Sport), automatic 4-point hydraulic leveling jacks, and dual-pane dark-tinted frameless windows with built-in night shades. Heat comes from Aqua-Hot diesel hydronic systems on the Super C diesel line, or the LP furnace and on-demand water heater setup on the Europa, Europa S, and Isata family.
The Xplorer Package: Dynamax's Off-Grid Upgrade
The Xplorer Package is Dynamax's off-grid upgrade option, available on most of the lineup (DX3, Dynaquest XL, Europa, Isata 5, Isata 6). It adds an insulated cab curtain and a lithium house battery upgrade. Capacity varies by product and production date, from 400aH on the Isata 5 to 720aH on later-production Dynaquest XL units. You also get a 1,000-watt solar package (vs. the standard 200W), an insulated utility bay with secondary tank heater and temperature sensor on most products, and the exclusive Xplorer paint schemes (Dark, Light, or Midnight). Planning extended boondocking, shoulder-season travel, or true off-grid use? Add the Xplorer Package to your floor plan.

Dynamax RV FAQs
Who makes Dynamax RVs?
Dynamax RV is a luxury Super C and Class C diesel motorhome builder based in Elkhart, Indiana. It's a subsidiary of Forest River Inc., which is owned by Berkshire Hathaway. The brand identity hasn't changed since founding: build Super C and luxury Class C motorhomes on commercial-grade chassis platforms (Freightliner M2 and Cascadia on the Super C lineup, Ram 5500 4x4 and Ford F-600 4x4 on the Class C lineup) with Class A diesel pusher-level amenities and luxury interior finishes.
What types of motorhomes does Dynamax build?
Dynamax builds two main families. Super C diesel: Grand Sport, DX3, Dynaquest XL, Europa S, and Europa on Freightliner Cascadia and M2 chassis. Class C diesel: Isata 6, Isata 5, and Isata 3 on Ford F-600 4x4, Ram 5500 4x4, and Mercedes Sprinter chassis. Every Dynamax comes with custom full-body paint, hardwood Shaker-style cabinetry, residential appliances, automatic 4-point hydraulic leveling, and all-aluminum no-wood construction.
What's the difference between a Super C and a Class C motorhome?
A Class C motorhome is built on a light-duty cutaway chassis, typically Ford E-Series gas, Mercedes Sprinter diesel, or Ram 3500/4500 diesel, with a truck cab attached to an RV body. A Super C is built on a medium-duty or heavy-duty commercial truck chassis, typically Freightliner M2, Freightliner Cascadia, or Ford F-550/F-600. The layout is similar, but a Super C carries much higher GVWR, GCWR, and towing capacity, plus a larger diesel engine. In the Dynamax lineup, the Grand Sport, DX3, Dynaquest XL, Europa S, and Europa are Super C products. The Isata 6 sits at the crossover between Class C and Super C despite its Ford F-600 chassis. The Isata 5 and Isata 3 are luxury Class C products.
Does Dynamax make 4x4 motorhomes?
Yes, two of them. The Dynamax Isata 5 rides on the Ram 5500 4x4 chassis with the Cummins 6.7L diesel. Its Extreme Package adds Liquid Springs smart suspension, a 4-inch rear / 2-inch front lift, super-single rear wheels, and 40-inch tires. The Dynamax Isata 6 rides on the Ford F-600 4x4 chassis with the 6.7L Power Stroke V8 and the DynaRide+ suspension package. Both are built for buyers who want Dynamax luxury with real off-pavement capability for boondocking, dispersed camping, and shoulder-season travel.
How does Dynamax compare to other Super C manufacturers?
Dynamax sits in the luxury Super C tier, competing mainly with Renegade, Thor Magnitude and Inception, Entegra Reatta and Accolade, Newmar Super Star, and Tiffin Allegro Bay at various tiers. What sets Dynamax apart: commercial-grade Freightliner M2 and Cascadia chassis across the lineup, standard air ride suspension and full air brakes, Aqua-Hot or Oasis hydronic heating, all-aluminum no-wood construction, and custom full-body paint as standard equipment. Buyers comparing Dynamax against ultra-luxury Class A diesel pushers (Foretravel World, Newmar King Aire, Entegra Cornerstone, Prevost conversions) often pick Dynamax when they want similar powertrains and amenities in a smaller, easier-to-drive Super C with a familiar truck cab.
What's the Aqua-Hot system used on Dynamax Super C products?
Aqua-Hot is a diesel hydronic heating system. One diesel-fueled unit provides both heated air and hot water, drawing from the coach's main fuel supply instead of a separate LP supply. The DX3 uses the Aqua-Hot 400D. The Dynaquest XL uses the Aqua-Hot 450D with engine pre-heat. The Grand Sport uses the larger Oasis hydronic system with continuous hot water. It's the same heating platform used in flagship Class A diesel pushers from Tiffin, Newmar, and Foretravel, and it costs less to run than the LP furnace and LP water heater setup on mainstream Class C and Super C products. The Europa, Europa S, and Isata family use the LP furnace and on-demand LP water heater instead.
What's the Xplorer Package?
The Xplorer Package is Dynamax's off-grid upgrade, available on most of the lineup (DX3, Dynaquest XL, Europa, Isata 5, Isata 6). It adds an insulated cab curtain, a lithium house battery upgrade, a 1,000-watt solar package (vs. the standard 200W), an insulated utility bay with secondary tank heater and temperature sensor on most products, and the exclusive Xplorer paint schemes (Dark, Light, or Midnight). It's built for extended boondocking, shoulder-season travel, and true off-grid use.
Is Dynamax a good RV brand?
Dynamax consistently ranks among the highest-rated luxury Super C and Class C diesel brands, with a strong reputation for chassis credentials, build quality, and long-term durability. If you want commercial-grade chassis platforms, Class A diesel pusher-level powertrains, all-aluminum no-wood construction, and luxury interiors, Dynamax is a strong choice in both segments. If you want a lower price point or a different chassis tier, mainstream-tier brands are the usual alternative.
Which Dynamax model should I buy?
It depends on how you travel and what you tow. Want the top of the Super C market? The Grand Sport (Freightliner Cascadia 126 tandem twin-screw, Detroit DD16 600HP, 80,000-pound GCWR). Serious tow capacity? The DX3 (Cummins L9 360HP, 20,000-pound hitch, five floor plans including a bunk model). Downsizing from a Class A diesel pusher and want the L9 at 450HP? The Dynaquest XL. A touring Super C with a roomier cab-over bunk? The Europa S. A more accessible Super C with the Cummins B 6.7L? The Europa. A 4x4 Super C? The Isata 6 (Ford F-600 4x4, 6.7L Power Stroke). A 4x4 luxury Class C with overland options? The Isata 5 (Ram 5500 4x4, Cummins 6.7L). The most compact and maneuverable Dynamax? The Isata 3 (Mercedes Sprinter chassis). The MHSRV sales team can help you narrow it down.
What's the difference between the Dynaquest XL and the DX3?
Both use the Cummins L9 turbo diesel and share Dynamax's signature features. The DX3 rides on the Freightliner M2 106 Plus chassis with the L9 at 360HP and 1,150 lb-ft, plus the Aqua-Hot 400D. The Dynaquest XL steps up to the Freightliner M2 112 PLUS chassis with the L9 at 450HP and 1,250 lb-ft, plus the Aqua-Hot 450D with engine pre-heat. The Dynaquest XL's 450HP L9 is the same powertrain used in Class A diesel pusher flagships like the Tiffin Phaeton, which makes it the natural pick for pusher owners moving to a Super C. Both offer the 20,000-pound trailer hitch.
Does Dynamax make a bunk model floor plan?
Yes. Two Super C products offer dedicated bunk floor plans: the DX3 37BD with twin bunk mattresses (28"x76"), a privacy partition, and two bunk CD/DVD players with monitors, and the Dynaquest XL 3700BD with the same bunk setup. Bunk-equipped Super C diesels are rare in a segment built mostly for couples. Several Dynamax products also offer the optional extended fiberglass front cap with a cab-over bunk mattress (50"x79") and privacy curtain for extra sleeping capacity.
