Dynamax Isata 5 RVs For Sale

Dynamax Isata 5 Series Class C diesel 4x4 motorhomes for sale at Motor Home Specialist, the #1 Volume Selling Motor Home Dealer in the World, and a full-line Dynamax RV Dealer. The Dynamax Isata 5 Series is a luxury Class C diesel motorhome built on the Ram 5500 4x4 chassis with the Cummins 6.7L I6 turbo diesel making 360 horsepower and 800 lb-ft of torque. Shopping for a new Isata 5 or a used Isata 5? MHSRV stocks one of the largest selections of Dynamax Isata 5 Series motorhomes for sale anywhere in the country, all backed by industry-leading discount pricing.

The Isata 5 fills a niche few luxury Class C builders compete in: a Ram 5500 4x4 chassis, the Cummins 6.7L diesel, a 10,000-pound trailer hitch, and a residential-quality coach build. If you want to drive your motorhome the way you'd drive a heavy-duty pickup, with familiar cockpit ergonomics, real 4x4 capability, and true towing capacity, this is the coach built for that. The Cummins powertrain also brings diesel fuel economy the gas-powered Class C field can't match, and the 4x4 opens up boondocking, dispersed camping, and shoulder-season travel that's harder to reach in a 2WD coach.

The Extreme Package

Where the Isata 5 really sets itself apart is the optional Extreme Package, available on both floor plans as the 28SSEX and 30FWEX. This isn't a cosmetic appearance package. It's a chassis-level reconfiguration. The Extreme Package replaces the standard four-point hydraulic leveling system with a Liquid Springs smart suspension featuring adjustable ride height and earth leveling. It lifts the chassis 4 inches in the rear and 2 inches in the front, swaps the dual rear wheels for super-single rear wheels, fits 40-inch tires on black aluminum wheels with custom wheel flares, adds an upgraded off-road front bumper with LED lights, and finishes with a black grille. Maximum height with the package is 13'1". That setup puts the Extreme Isata 5 in direct competition with adventure-class Super C products like the Thor Magnitude and Omni, the Renegade Veracruz, and the Nexus Wraith, in a more compact and maneuverable Class C footprint. One note for Extreme buyers: Adaptive Cruise Control may be disabled under certain weather or road conditions. The higher ride height can increase how often that happens. Standard Cruise Control remains available in those situations.

Chassis, Power, and Towing

Every Isata 5 is built on the Ram 5500 factory 4-wheel-drive chassis with a 19,500-pound GVWR and a 37,500-pound GCWR. The Cummins 6.7L I6 turbo diesel makes 360 horsepower and 800 lb-ft of torque. The transmission varies by production date: earlier builds use the Ram 5500 SLT chassis with the AISIN HD 6-speed automatic and a 4.89 rear axle ratio, while recent production units use the upgraded Ram 5500 Big Horn chassis with the 8-speed TorqueFlite HD automatic and a 4.44 rear axle ratio. Both configurations share the 10,000-pound trailer hitch with 750-pound tongue capacity, the 52-gallon fuel tank, the 9-gallon DEF tank, dual 220-amp alternators (440 amps total), the Cummins Smart Exhaust Brake System, the Ram OEM trailer brake control, B-20 biodiesel capability, and 4-wheel ABS. Dynamax adds its DynaRide+ upgraded suspension: four-point Bilstein gas-charged shock absorbers, rear MORryde RSX rubber shear springs, and a heavy-duty rear sway bar. Standard tires on non-Extreme floor plans are 225/70R19.5G all-position front and rear traction tires on single front and dual rear 19.5-inch wheels. The Ram ESC Suspension and Stability Package and a Tire Pressure Monitoring System are standard.

Driver-Assist Tech and Cockpit

The Ram 5500 chassis brings a driver-assist suite that's unusual for a Class C: Active Brake Assist, Adaptive Cruise Control, Lane-Keep Assist, Traffic Sign Recognition, and Auto High Beam Headlamp Control. Standard cockpit features include heated leatherette reclining driver and passenger seats with armrests, a power driver seat with power lumbar, a heated steering wheel with adjustable column, power-heated exterior mirrors with courtesy lamps and turn signals, a Quad-View camera system (right side, left side, hitch, and rear horizon views), remote start, and rain-sensitive windshield wipers. Infotainment also varies by production date: earlier builds use the 8.4-inch U-Connect touchscreen with Bluetooth, Apple CarPlay, Android Auto, 4G LTE Wi-Fi hotspot readiness, and six speakers, while recent production units use the 12-inch U-Connect 5 Nav system with HD Radio, SiriusXM 360L readiness, Alexa readiness, and six premium speakers.

Construction

The Isata 5 uses 2-inch aluminum-framed laminated sidewalls with high-density block foam insulation, composite exterior fiberglass with no exterior wood anywhere, an aluminum-framed floor with a lightweight moisture-resistant composite substrate, aluminum-framed roof trusses with a crowned one-piece fiberglass roof, foil-lined ductwork throughout, a fiberglass front cap and front wing panels, and smooth rotocast storage compartments with LED lighting and side-hinged locking aluminum doors with paddle latches. The all-aluminum, no-wood build supports long-term durability in adventure-travel use where wood-framed Class Cs would see structural fatigue over time.

Power and Off-Grid Systems

The standard Isata 5 comes with low-temp lithium auxiliary batteries, a 3,000-watt hybrid pure sine wave inverter/charger, an 8 kW Onan diesel generator with auto transfer switch and automatic generator start (mounted on isolator pads), a 200-watt glass solar panel with 30-amp controller, 50-amp service with a 30-foot detachable power cord, an Energy Management System, and Firefly multiplex wiring with a touchscreen command center, switch panels, and Bluetooth smartphone app control. Battery capacity has grown through running changes: earlier builds carry dual lithium batteries totaling 200 amp-hours, while recent production units carry up to three lithium house batteries totaling 720 amp-hours. The 8 kW diesel generator pulls from the same 52-gallon diesel tank as the engine. That's an operating-cost advantage over gas Class Cs, which need a separate LP supply. Climate is handled by dual ducted low-profile 15,000 BTU air conditioners with heat pumps, a 40,000 BTU LP furnace with electronic ignition, and a 60,000 BTU Truma AquaGo Comfort Plus on-demand LP water heater.

The optional Xplorer Package upgrades further with dual-pane dark-tinted frameless windows, an insulated cab curtain, four lithium house batteries, a 1,000-watt solar package, an insulated utility bay with a secondary tank heater and temperature sensor, and access to the exclusive Xplorer paint schemes (Dark, Light, or Midnight). Every Isata 5 also comes prepped for a roof-mounted Starlink satellite internet system and a roof-mounted satellite TV dish. A Winegard over-the-air HDTV antenna is standard, along with a cable/satellite hookup in the service bay and a 4x4 HDMI matrix for routing video to the coach's TVs.

Exterior

The Isata 5 comes standard with custom full-body paint with a premium cut-and-buffed finish, front-end Diamond Shield paint protection, an armless patio awning with LED lighting and motion-activated retraction, slideout toppers, an LED patio light, an entry door with rotary latch and dark-tinted frameless window with integrated shade, a keyless entry touch pad, remote key fob entry integrated with the chassis key fob, a lighted acrylic entry grab handle, power entry steps with SeaDek treads, front and rear LED clearance and marker lighting, rear LED docking lights, the rear DYNAMAX rock guard, and aluminum running boards. The 30FW includes an exterior wall-mounted entertainment center with a 32-inch LED Smart TV. The 28SS includes an exterior TV mount with a portable bedroom TV that doubles for outside use. Recent production units come standard with dual-pane acrylic windows with built-in night shades and screens, a meaningful upgrade for cold-weather and full-time use.

Inside the Isata 5

Both floor plans feature premium vinyl flooring, a soft-touch padded vinyl ceiling, dimmable LED recessed ceiling lights, hardwood Shaker-style cabinetry with full-extension soft-closing drawer guides and hidden hinges, sprung residential-style dinette seats with lift-up storage, blackout roller shades, magnetic thermal reflective front privacy shades, a 42-inch LED Smart TV in the living area with a JBL sound bar, USB and USB-C charging ports throughout, and a front cab-over bunk with a 50-by-80-inch mattress and privacy curtain. The kitchen includes a gas range with glass cover, a convection microwave with air fryer function, solid-surface countertops with LED edge lighting and a decorative backsplash, a stainless steel sink with roll-up slotted covers, a residential stainless gooseneck faucet, a pantry, overhead cabinet accent and under-cabinet lighting, and a MaxxAir power vent with built-in rain cover.

The master bedroom has a 60-by-75-inch Queen bed with a gel-infused memory foam mattress, a designer bedding package, a 32-inch LED Smart TV, a cedar-lined wardrobe, LED reading lights, and USB/USB-C charging ports. Both baths share a shower skylight, an Oxygenics Body Spa shower head, a stainless steel sink with residential faucet, and a MaxxAir power vent.

The Isata 5 Floor Plans

At MHSRV, the Isata 5 comes in two floor plans, each also available in Extreme Package trim (28SSEX and 30FWEX).

The 28SS runs 31'2" overall on the 217-inch wheelbase. It's the more compact and maneuverable layout, with a single rear-bedroom slide, a standard booth dinette, the 12V 10-cubic-foot compressor-driven refrigerator, a deluxe padded headboard in the master, a 26-by-36-inch designer shower with a glass door, and a porcelain electronic-flush macerator toilet.

The 30FW runs 33'3" overall on the 238-inch wheelbase. It's the larger dual-slide layout, with a Queen bed in the rear slide, a booth dinette plus sofa in the living-room slide, a 16-cubic-foot residential refrigerator with ice maker standard (the 12V compressor refrigerator is optional in its place), the larger 36-by-36-inch designer shower with a soft-sided door, and a porcelain foot-flush toilet. The 12V compressor refrigerator is the better pick for extended boondocking off shore power; the residential refrigerator suits buyers who want ice maker capacity.

Cross-shopping the Isata 5? Within the Dynamax lineup at MHSRV, also consider the Isata 3 (the Sprinter-based smaller Class C), the Isata 4 (the mid-tier Class C diesel), and the Isata 6 (the larger 4x4 Super C above the Isata 5).
