New 2026 Entegra Coach ARC 18C Motor Home Class B

The 2026 Entegra Coach ARC 18C is a compact, easy-to-drive Class B gas motorhome built on the RAM ProMaster 1500 chassis with a 3.6L V6 engine (276 HP). Designed for agility and everyday usability, it measures just under 18 feet in length, making it ideal for city driving, national parks, tight campsites, and garage-friendly storage. With no slideouts and a highly efficient layout, the ARC 18C focuses on mobility, simplicity, and smart space utilization for couples or solo travelers.

Inside, the layout is engineered around maximum function in minimal space. The front living area features a flexible lounge that converts into sleeping space, paired with swivel cab seats to expand usable interior seating. The rear of the coach contains a fully equipped wet bath and integrated wardrobe storage, creating a self-contained travel setup without sacrificing livability. The interior design emphasizes clean finishes, durable materials, and practical storage solutions throughout.

The galley kitchen is positioned mid-coach and includes a compact refrigerator, microwave, stainless sink, and cooktop, supported by overhead and lower cabinetry for efficient storage. Everything is placed for accessibility and movement efficiency, making it easy to cook, clean, and travel comfortably in a small footprint.

Technology and systems are built for real-world travel flexibility. The ARC 18C includes LED lighting, touchscreen infotainment with Apple CarPlay/Android Auto, backup camera system, climate control, and integrated safety systems such as lane assistance and collision mitigation. With onboard power systems, water storage, and optional solar capability, it supports both campground hookups and off-grid stays.

Driving the ARC 18C feels similar to a large SUV rather than a traditional RV, giving owners confidence whether navigating highways, parking downtown, or exploring remote routes. It’s designed for travelers who prioritize simplicity, fuel efficiency, and ease of ownership without giving up essential comforts.
