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 engine producing 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 occupies a specific niche in the luxury Class C market that very few competitors actually compete in: a Ram 5500 4x4 chassis paired with the Cummins 6.7L diesel, a 10,000-pound trailer hitch, and a residential-quality coach build that turns the truck-cab driving experience into a genuine alternative to a Class A or larger Super C. For buyers who want to drive their motorhome like they'd drive a heavy-duty pickup — familiar cockpit ergonomics, real 4x4 capability, true towing capacity — the Isata 5 is what they're shopping. The Cummins powertrain delivers diesel fuel economy that the gas-powered Class C field can't match, the Ram cockpit feels familiar to truck owners stepping up to a motorhome, and the 4x4 capability opens up boondocking, dispersed camping, and shoulder-season travel that's harder to access in a 2WD coach.

Where the Isata 5 really differentiates itself, though, is the optional Extreme Package — available on both floor plans as the 28SSEX and 30FWEX. The Extreme Package replaces the standard four-point hydraulic leveling system with a Liquid Springs smart suspension featuring adjustable ride height and earth leveling, 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, replaces the standard front bumper with an upgraded off-road bumper with LED lights, and finishes with a black grille. The maximum height with the Extreme Package extends to 13'1". This isn't a cosmetic appearance package — it's a chassis-level reconfiguration that puts the Extreme Isata 5 in direct competition with adventure-class Super C products like the Thor Magnitude/Omni, the Renegade Veracruz, and the Nexus Wraith, in a meaningfully more compact and maneuverable Class C footprint.

Under the hood, every Isata 5 is built on the Ram 5500 factory 4-wheel-drive chassis (19,500-pound GVWR, 37,500-pound GCWR) with the Cummins 6.7L I6 turbo diesel engine producing 360HP and 800 lb-ft of torque. The transmission depends on production date: units built before SGC007238 use the AISIN HD 6-speed automatic with a 4.89 rear axle ratio (Ram 5500 SLT chassis); units built starting at SGC007238 use the upgraded Ram 5500 Big Horn chassis with the 8-speed TorqueFlite HD automatic transmission and a 4.44 rear axle ratio. Both configurations share the Cummins 6.7L diesel powertrain, the 4x4 capability, the 10,000-pound trailer hitch with 750-pound tongue capacity, the 52-gallon fuel tank, the 9-gallon DEF tank, the dual 220-amp alternators (440 amps total), the Cummins Smart Exhaust Brake System, the Ram OEM trailer brake control, and 4-wheel ABS.

The Isata 5 chassis includes Dynamax's DynaRide+ upgraded suspension system, which adds four-point Bilstein gas-charged shock absorbers and rear MORryde RSX rubber shear springs with a heavy-duty rear sway bar to the base Ram 5500 chassis. Standard tires on non-Extreme floor plans are 225/70R19.5G all-position front and rear traction tires, on single front wheels and dual rear wheels (19.5"x6"). The Ram ESC Suspension and Stability Package and Tire Pressure Monitoring System are standard.

The Ram 5500 chassis brings a comprehensive standard ADAS 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 control, 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 depends on production date: pre-SGC007238 units use the 8.4" U-Connect touchscreen with Bluetooth, Apple CarPlay, Android Auto, 4G LTE Wi-Fi hotspot ready, and six speakers; post-SGC007238 units use the 12" U-Connect 5 Nav system with HD Radio, SiriusXM 360L Ready, Alexa Ready, and six premium speakers.

Note for Extreme Package buyers: Adaptive Cruise Control may be disabled under certain weather or road conditions, and the frequency of disablement may be increased due to the Extreme Package's higher ride height. Standard Cruise Control remains available in those situations.

For coach construction, the Isata 5 uses 2-inch aluminum-framed laminated sidewalls with high-density block foam insulation, composite exterior fiberglass (no exterior wood anywhere), an aluminum-framed floor with composite flooring substrate, aluminum-framed roof trusses with a crowned one-piece fiberglass roof, foil-lined ductwork throughout, fiberglass front cap and front wing panels, and seamless rotocast storage compartments with LED lighting and side-hinged locking aluminum exterior doors with paddle latches. The all-aluminum, no-wood construction philosophy reflects the Isata 5's premium positioning and supports long-term durability in adventure-travel use cases where conventional wood-framed Class Cs would see structural fatigue.

For electrical and off-grid capability, the standard Isata 5 ships with dual low-temp lithium auxiliary batteries (200aH total), a 3,000-watt hybrid pure sine wave inverter/charger, an 8kW Onan diesel generator with auto transfer switch (mounted on isolator pads), a 200W glass solar panel with 30-amp controller, 50-amp service with a 30-foot detachable power cord, an automatic generator start, an energy management system, and Firefly multiplex wiring with a touchscreen command center, switch panels, and Bluetooth smartphone app control. 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 Isata 5's off-grid capability has been expanding with running changes. Units built starting at SGC007392 ship with dual low-temp lithium auxiliary batteries totaling 480aH (vs. the earlier 200aH configuration), and the 28SS units at SGC007500 and 30FW units at SGC007392 ship with three lithium house batteries totaling 720aH. The optional Xplorer Package upgrades further with dual-pane dark-tinted frameless windows, an insulated cab curtain, four lithium house batteries (400aH total), a 1,000-watt solar package, an insulated utility bay with secondary tank heater and temperature sensor, and access to the exclusive Xplorer paint scheme options (Dark, Light, or Midnight). This Xplorer configuration is what puts the Isata 5 squarely in serious off-grid territory for buyers who want extended boondocking and shoulder-season capability without aftermarket battery and solar upgrades.

The Isata 5 ships 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, keyless entry touch pad at the entry door, remote key fob entry (integrated with the chassis key fob), a lighted acrylic entry grab handle, power entry steps with upgraded SeaDek step treads, front and rear LED clearance and marker lighting, rear LED docking lights, the rear DYNAMAX rock guard, and aluminum running boards. The 30FW floor plan includes an exterior wall-mounted entertainment center with a 32" LED Smart TV; the 28SS includes an exterior TV mount with a portable bedroom TV that doubles for exterior use.

Inside the Isata 5, both floor plans feature premium vinyl flooring throughout, 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" 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 area with a 50"x80" mattress and privacy curtain. Units starting at SGC007255 ship with dual-pane acrylic windows with built-in night shades and screens as standard (a meaningful upgrade for cold-weather and full-time use).

The Isata 5 kitchen layout is built around a 16-cubic-foot residential refrigerator with ice maker (on the 30FW standard configuration) or a 12V 10-cubic-foot 2-door compressor-driven refrigerator (standard on the 28SS, 28SS Extreme, and 30FW Extreme; optional in place of the residential refrigerator on the 30FW). The kitchen also includes a gas range with a glass cover, a convection microwave with air fryer functionality, solid surface countertops with LED edge lighting and a decorative backsplash, a stainless steel sink with roll-up stainless slotted covers, a residential stainless gooseneck faucet, a pantry, overhead cabinet accent lighting, under-cabinet lighting, and a MaxxAir power vent with built-in rain cover. The compressor-driven refrigerator option is the natural choice for buyers who plan extended boondocking off shore power, while the residential refrigerator is the natural choice for buyers who prioritize ice maker capacity and prefer the traditional residential layout.

The Isata 5 master bedroom features a Queen-size 60"x75" bed with a gel-infused memory foam mattress, designer bedding package, a 32" LED Smart TV, a cedar-lined wardrobe, LED reading lights, USB and USB-C charging ports, and (on the 28SS) a deluxe padded headboard. Bath layout varies by floor plan: the 28SS uses a 26"x36" designer shower with a glass shower door and a porcelain electronic-flush macerator toilet, while the 30FW uses a larger 36"x36" designer shower with a soft-sided shower door and a porcelain foot-flush toilet. Both share a shower skylight, an Oxygenics Body Spa RV shower head, a stainless steel sink with residential faucet, and a MaxxAir power vent.

Cross-shopping the Isata 5?

For buyers shopping the broader 4x4 luxury Class C / Super C segment, external cross-shop typically includes the Thor Magnitude and Omni Trail (Ford F-550 / F-600 4x4 Super C), the Renegade Veracruz (Ram 5500 4x4-based competitor), and the Nexus Wraith, all available at Motor Home Specialist alongside the Dynamax lineup.
