2027 Winnebago Arka 20Z River Stone

20Z Floorplan
The ARKA™ 20Z is a modular layout designed to flex easily between rest, work, and gear storage without permanent compromises. The convertible front bunk configures as a king, queen, or twin beds, while the rear dinette converts to a large bed, bringing total sleeping capacity to four. That same rear dinette space transforms into a full-height, full-width heated gear garage, with van-style doors that keep your loadout organized and easy to access. Aluminum cabinetry with lockable compression latches, durable countertops, and easy-clean surfaces hold up to real use, and a hidden shower and cassette toilet mean you're never roughing it.

Features May Include:

Backcountry Cred

• ARKA is built from the ground up for backcountry adventures. A clean underbody pairs with a torsion free, four-point pillow-block system that lets the box and cab move with the terrain. Up top, its one-piece molded fiberglass roof sheds water and withstands years of trail vibration, while a 15,000 lb towing capacity means you can bring whatever the trip demands.

All-Season Comfort

• The ARKA is engineered to operate from -10°F to 120°F. With hydronic heating, heated floors and tanks, and R-15 roof and R-12 wall insulation, this rig performs in conditions that send others home. A first-of-its-kind heat recovery ventilation system in the RV industry manages humidity, mitigates condensation, and provides fresh air for year-round comfort.

Extended Off-Grid Independence

• Go up to 14 days off-grid, powered by a 48V energy architecture with up to 16.8 kWh of lithium battery capacity, up to 800W of expandable solar, and fast auxiliary alternator charging. With a 60-gallon heated and insulated fresh water tank and a 40-gallon heated and insulated gray water tank, you can stop budgeting power and water and spend more time enjoying wherever you've landed.

Modern and Modular

• A full-height, heated rear gear garage with van-style doors anchors a thoughtfully designed interior that’s built to get dirty and clean up easily. L-track mounting systems secure gear, aluminum cabinetry won’t swell or delaminate, and convertible sleeping configurations accommodate couples, families, or gear-heavy trips without compromise.

Smarter, Connected Control

• With Winnebago Connect, you can control and monitor your coach from your phone, with offline pairing support. Track power and tanks, monitor real-time pitch and roll to help on the trail and with leveling your truck, manage multi-zone climate, and access features like door locks and Pet Minder alerts. Stay connected wherever you land with available connectivity options and optional Starlink® integration.

Customize Your Adventure

• Outfit your ARKA with a curated line of adventure-ready accessories designed to upgrade, organize, and evolve your rig over time. From modular storage systems that transform your gear garage to bolt-on exterior and interior accessories, each addition is built to adapt to your needs.
