The chassis is one of the most overlooked aspects of choosing a high-quality motor coach. As the foundation of your motorhome, a well-crafted chassis plays an important role in how much – or how little – you enjoy traveling from coast to coast in your Class A RV.
Given our commitment to industry-leading quality and engineering, Newmar works closely with the world’s best chassis manufacturers — Ford, Freightliner Custom Chassis and Spartan Motors — to equip each of our coaches with a strong and durable platform. It’s all about delivering our customers with the best in on-road comfort, maneuverability, and safety technology.
THE star foundation
The STAR Foundation is a precisely engineered, Newmar-exclusive steel superstructure designed to improve chassis strength and durability, while delivering a ride that is quieter and more stable. The STAR Foundation is carefully welded to every Newmar diesel and luxury chassis inside of our own in-house welding facility.
