<h3>About AP Products</h3><p><strong>AP Products</strong> has been a cornerstone of the recreational vehicle industry for over three decades. Founded in 1994 by Tom Manning Sr. — with roots going back to 1992 — the company began with a straightforward goal: offering a complementary line of packaged screws to support an existing supplier relationship. What started as a niche hardware offering has since grown into one of the most comprehensive RV replacement parts portfolios in North America.</p><p>Headquartered in Coldwater, Michigan, AP Products serves both the OEM and aftermarket segments of the RV world. Their catalog spans everything from adhesives and sealants to electrical components, braking systems, doors, locks, seals, and slide-out parts — making them a true one-stop source for RV dealers and enthusiasts alike. The company operates a group of 13 brands, focused on bringing high-quality, often American-made products to market and filling gaps that other suppliers have overlooked.</p><h3>A Broad Product Range Built Around RV Life</h3><p>One of AP Products' most recognized product segments is <a href="/2843-ap-body-trim-molding-46915">body trim molding</a>. Whether you&apos;re restoring a sun-faded travel trailer or refreshing a Class A motorhome, AP Products offers aluminum insert trim molding in a range of finishes — including Polar White, Colonial White, Black, and Mill Finish — designed to fit securely and deliver a clean, factory-like appearance. These trim solutions are made in the USA and backed by a limited warranty.</p><p>Lighting is another area where AP Products shines. Through their StarLights sub-brand and their broader electrical lineup, AP Products offers a wide array of <a href="/2843-ap-driving-light-bulb-16367">driving light bulbs</a> and RV-specific lighting solutions. From LED replacement bulbs engineered to fit standard RV fixtures to specialized omnidirectional tower bulbs, their lighting products are designed to deliver reliable performance and energy efficiency for life on the road.</p><p>Beyond trim and lighting, AP Products&apos; electrical category is expansive — covering adapters, circuit breakers, converters, power centers, energy management systems, awning accessories, and more. Their hardware line covers both exterior and interior needs, from compartment hardware and screw covers to cabinet hardware sized to fit travel trailers, fifth wheels, Class A and Class C motorhomes, and toy haulers.</p><h3>Trusted by RV Dealers and Owners Nationwide</h3><p>AP Products has built its reputation not just on product breadth, but on a genuine commitment to supporting the dealer network. The company has managed dozens of national retail and OEM accounts, and their parts are stocked widely to ensure availability when and where RV owners need them most. Quality is monitored continuously throughout production, reflecting a brand philosophy centered on reliability over the long haul.</p><p>Whether you&apos;re a seasoned full-timer, a weekend camper, or an RV service technician, AP Products delivers the parts and confidence to keep any rig road-ready.</p>
