<h3>Suburban Mfg: Over 75 Years of RV Comfort Innovation</h3><p><strong>Suburban Manufacturing</strong>, an <a href="/7593-suburban-mfg">Airxcel brand</a> headquartered in Dayton, Tennessee, has been one of the most recognized names in the RV industry since its founding in 1947. What began as a small gas space heater company evolved into a powerhouse of RV comfort technology — a transformation driven by a single customer request to adapt a greenhouse heater for use in a motorhome. That spark of ingenuity set Suburban on a course that would define RV living for generations.</p><p>Throughout the late 1960s and beyond, Suburban's engineers pioneered some of the most important advances in RV appliance design: space-saving, horizontally vented gas heating systems, solid-state spark ignition systems, efficient DC furnace motors, and on-demand water heating. In 1998, Suburban became part of the Airxcel family of brands — the largest privately held supplier to the RV industry — further expanding its reach and resources while maintaining its deep roots in Dayton, Tennessee, where it operates a 300,000-square-foot manufacturing facility.</p><h3>A Complete Lineup for RV Comfort</h3><p>Today, Suburban is the go-to brand for RV owners who demand reliability and performance. Their <a href="/7593-suburban-mfg-water-heaters-201162">RV water heaters</a> are among the most trusted on the market, available in propane, electric, and combination models in a range of tank sizes — including their innovative Advantage Direct Fit line designed for easy replacement. For the galley, Suburban's <a href="/7593-suburban-mfg-stoves-cooktops-201021">stoves and cooktops</a> bring thoughtful engineering to compact RV kitchens, from traditional gas ranges to modern induction cooktops with glass tops that double as extra counter space when not in use.</p><p>Behind every Suburban appliance is a robust ecosystem of heating parts and accessories — including furnace gaskets, combustion air housings, igniter electrodes, thermocouples, and circuit boards — making it easy to service and maintain Suburban systems for years to come. The brand's commitment to quality means most products undergo rigorous testing before leaving the factory, and much of the product line is backed by a 2-year limited warranty.</p><h3>Innovation That Keeps Moving Forward</h3><p>Suburban has never been content to rest on its legacy. The brand introduced glass range tops to the RV world, giving campers the flexibility of a larger working surface. More recently, they launched the RV One — a patent-pending combination water heater and furnace unit engineered specifically for compact travel trailers and lightweight RVs. This all-in-one approach exemplifies Suburban's guiding philosophy: deliver maximum comfort while respecting the space and weight constraints unique to the RV lifestyle.</p><p>Whether you're replacing an aging water heater, upgrading your cook space, or sourcing a hard-to-find furnace part, Suburban Mfg delivers the quality, innovation, and reliability that RV enthusiasts have counted on for more than seven decades.</p>
