Atwood Mobile

<h3>Atwood Mobile Products: Over a Century of RV Innovation</h3><p><strong>Atwood Mobile Products</strong> has been bringing the comforts of home to the open road since its founding in 1909 by brothers James and Seth Atwood. What began as the Atwood Vacuum Machine Company in Rockford, Illinois gradually evolved into one of the most recognized names in the recreational vehicle industry. Through decades of strategic growth and product development, Atwood became the go-to manufacturer of essential RV appliances — earning a reputation built on durability, reliability, and engineering excellence.</p><p>The company's trajectory into the RV market accelerated through a series of key acquisitions. In 1964, Atwood purchased the Bowen Company, an established RV water heater manufacturer, planting the seeds for what would become its most iconic product line. The mid-1980s acquisition of Wedgewood brought a full lineup of gas ranges and cooktops into the fold, and the 1993 purchase of Hydroflame furnaces solidified gas appliances as the core of Atwood's identity. By 2010, the company had further expanded with the addition of Fan-Tastic Vent, a respected manufacturer of performance air-exchange systems. In 2014, Dometic acquired Atwood Mobile Products, and Atwood products continue to be manufactured and sold under the Dometic umbrella — carrying forward a legacy that touches virtually every corner of the RV market.</p><p>According to industry sources, Atwood products are found in approximately 90 percent of recreational vehicles in America — a testament to the brand's widespread trust among RV builders and owners alike. Whether you're outfitting a new rig or replacing a worn component, Atwood's lineup covers the essentials that make mobile living comfortable and safe.</p><h3>Atwood's Core Product Categories</h3><p>Atwood's strength lies in the breadth and quality of its appliance lineup. The brand's <a href="/6692-atwood-mobile-water-heaters-201162">RV water heaters</a> are perhaps its most celebrated products, available in propane, electric, and on-demand tankless configurations to suit a wide range of needs and rig sizes. Their aluminum tank construction is engineered to resist corrosion — a critical advantage in mobile environments where moisture and road wear take a constant toll.</p><p>For warm-weather travel, Atwood's <a href="/200073-air-conditioning-atwood-mobile-6692">RV air conditioning</a> units provide efficient, quiet rooftop cooling that keeps interiors comfortable even in peak summer heat. Designed specifically for the demands of mobile use, these units balance powerful output with energy-conscious operation.</p><p>In the galley, Atwood's <a href="/201021-stoves-cooktops-atwood-mobile-6692">RV stoves and cooktops</a> — developed through the Wedgewood line — offer a wide selection of gas cooking options that bring real home-cooking capability to any camper or motorhome. And for maintaining a fully functioning RV bathroom and kitchen, the brand's <a href="/6692-atwood-mobile-plumbing-parts-accessories-200786">plumbing parts and accessories</a> provide the connectors, fittings, and hardware needed to keep water systems running properly on the road.</p><p>Atwood Mobile Products remains a cornerstone brand for RV owners, DIY enthusiasts, and professional technicians seeking dependable replacement parts and appliances. With a service network spanning thousands of locations across North America, support for Atwood products is never far away.</p>
