McKee RV - Which chassis is right for family trips around Omaha, NE: 2026 Dynamax Isata 5 or 2026 Dynamax Isata 6?
Choosing between the Ram 5500-based Dynamax Isata 5 and the Ford F600-based Dynamax Isata 6 often starts with one question: which chassis best supports family trips with towing, storage, and off-grid ambitions around Omaha, NE? Both are true 4x4 Class C motorhomes with full-body paint, DynaRide+ upgraded suspension components, dual low-profile 15,000-BTU A/Cs with heat pumps, an 8kW Onan diesel generator, Firefly Multiplex controls, and a Truma AquaGo Comfort Plus on-demand water heater. Yet the personalities of these coaches differ in ways that matter on travel day and at the campsite.
The Isata 6 leans into towing and range with a 22,000-lb GVWR, a 43,500-lb GCWR, a 15,000-lb hitch rating, and a 66.5-gallon fuel capacity. Ford’s Power Stroke 6.7L V8 Turbo Diesel is paired to a TorqueShift 10-speed automatic, adding tightly spaced ratios that help with grade changes and merging. Safety and driver-assistance tech includes AdvanceTrac with RSC, audible Lane Departure Warning, Pre-Collision Assist with Automatic Emergency Braking, and the SOS Post-Crash Alert System. Inside the cab, SYNC 4 with an 8" touch screen integrates Apple CarPlay, Android Auto, and FordPass Connect 5G for reliable, modern connectivity on the move.
The Isata 5 counters with the Ram 5500 chassis, Cummins 6.7L I6 Turbo Diesel, and AISIN HD 6-speed automatic. Power delivery feels relaxed and predictable, and the Ram ESC suspension and stability package, Adaptive Cruise Control, Lane-Keep Assist, and Active Brake Assist support calm confidence. A running change to the Ram 5500 Big Horn brings a 12" U-Connect 5 Nav infotainment center on many units, which families appreciate for split-screen mapping and media. For backroads and soft access paths, the Extreme Package adds Four-Point LiquidSpring smart suspension with adjustable ride height and earth-leveling, a lifted chassis, super-single rear wheels, and 40" tires—upgrades that smooth ruts and reduce head-toss over washboard surfaces.
Inside, both series split the difference between lounge comfort and durable, easy-clean finishes. The Isata 6 offers the 31KS with an induction range and theater seating, while the 30FW includes a tri-fold sofa and a 36"x36" shower. The Isata 5 28SS and 30FW combine residential touches—solid-surface counters with LED edge lighting, glass-covered ranges, and thoughtfully lit cabinets—with practical layouts, including a 26"x36" shower in 28SS and a 36"x36" shower in 30FW. In either series, the cab-over bunk adds family-ready sleeping, and living-area SMART TVs with JBL sound create an at-home movie-night feel.
Families weighing regular towing of side-by-sides or a larger boat will gravitate to the Isata 6’s 15,000-lb hitch rating and higher GCWR. Owners who prioritize backcountry trailheads, uneven campsites, or seasonal roads benefit from the Isata 5’s Extreme Package with LiquidSpring and lifted stance. Both models are prepped for roof-mounted Starlink Satellite Internet, making remote coursework or work-from-camp possible, and both can be optioned with the Xplorer Package to expand lithium capacity and solar output for longer boondocking windows.

For most families, the decision comes down to tow weight and terrain. If a 15,000-lb trailer is part of the plan, the Isata 6 is the straightforward match. If access roads or unlevel campsites are common, the Isata 5 with the Extreme Package offers remarkable composure without sacrificing the premium amenities both series share.
Frequently Asked Questions:
Can both models comfortably tow a car hauler or boat?
Yes, but within ratings. The Isata 6 is rated to 15,000 lbs and better fits heavier car haulers or larger boats. The Isata 5 is rated to 10,000 lbs, which covers many cargo and utility trailers and a wide range of fishing boats.
Which coach is better for boondocking?
Both do well with standard lithium batteries, a 200W solar panel with a 30-amp controller, and an 8kW Onan diesel generator. Selecting the Xplorer Package on either expands lithium capacity and solar to 1,000W. The Isata 5’s Extreme Package adds ride height and Four-Point LiquidSpring smart suspension, which can help reach remote sites more comfortably.
How do the safety and driver-assist systems compare?
The Isata 6 integrates Ford AdvanceTrac with RSC, audible Lane Departure Warning, and Pre-Collision Assist with AEB. The Isata 5 features Ram ESC, Lane-Keep Assist, Adaptive Cruise Control, Active Brake Assist, and Traffic Sign Recognition.
