Demco Trailer

<h3>About Demco Trailer Products</h3><p>When it comes to dependable towing hardware, Demco has built a reputation that spans decades. Headquartered in Madison, Wisconsin, Demco Products is a privately held American manufacturer that has become a trusted name among trailer builders, RV enthusiasts, and heavy-duty haulers alike. What sets Demco apart is a straightforward philosophy: engineer components that are stronger, easier to use, and longer-lasting than the competition — and back them with a warranty that reflects that confidence.</p><p><strong>Made in the USA</strong>, Demco's trailer components are manufactured and assembled to rigorous quality standards, ensuring safety and dependability for every towing application. From light utility trailers to agricultural rigs and RVs, Demco's product range is designed to handle demanding real-world conditions without compromise.</p><h3>The EZ Latch Advantage</h3><p>At the heart of Demco's product lineup is the iconic EZ Latch mechanism. Unlike conventional couplers that require manual engagement, the Demco EZ Latch automatically latches when lowered onto a hitch ball — no extra steps, no fumbling, no guesswork. The system meets and exceeds all SAE J684 safety requirements and is entirely maintenance-free, requiring no grease or periodic adjustments. The composite latch handle is engineered to resist impact and corrosion, and it's backed by a limited lifetime warranty. For anyone who regularly hitches and unhitches trailers, this level of reliability is a genuine quality-of-life upgrade.</p><p>Demco's <a href="/10889-demco-trailer-trailer-coupler-16540">trailer couplers</a> come in a wide variety of configurations to suit virtually any trailer type. Whether you need an A-frame, channel mount, flat mount, or tube mount style, and whether you're towing at 7,000 lbs or 21,000 lbs GVWR, there's an EZ Latch coupler sized and rated for your needs. Many models also carry a 500-hour salt spray rating, making them well-suited for marine and boat trailer use.</p><h3>Fifth Wheel Hitches and Ball Mounts</h3><p>Beyond couplers, Demco has developed a respected line of <a href="/200129-ball-mountsreceivers-demco-trailer-10889">ball mounts and receivers</a>, including their Premier Series and Recon Series fifth wheel hitches. The Recon line is designed for trucks using a recessed gooseneck ball setup, featuring a lightweight two-piece construction that makes installation and removal quick and straightforward. With multiple vertical height adjustments and no need for adapter plates or pin box modifications, the Recon series exemplifies Demco's commitment to practical, driver-friendly engineering. These hitches are made in the USA and engineered to the same exacting standards as the rest of the Demco product family.</p><h3>A Brand Towing Professionals Trust</h3><p>Demco's products appear as standard equipment on trailers from well-known manufacturers across the country — a testament to the brand's reputation among trailer builders and industry professionals. Whether you're replacing a worn coupler, upgrading your fifth wheel hitch setup, or outfitting a new trailer build, Demco offers the components to do the job right, with the engineering pedigree and warranty support to match.</p>

Product Details

The Demco 6271 SMI Air Force One Second Car Kit is an essential accessory for RV owners who want to equip an additional towed vehicle to work with their existing Air Force One supplemental braking system. This kit allows you to use your Demco SBS Air Force One supplemental braking system with an additional vehicle, eliminating the need to purchase an entirely new braking system when towing multiple cars.

System Overview:

The kit includes all parts required to install Air Force One on a second car, including wiring, air lines, and mounting hardware. This Second Car Kit comes with Wiring, Air Lines and Hardware necessary for a complete installation. The Air Force One system is designed exclusively for motorhomes equipped with air brakes, making it ideal for diesel pusher coaches.

Key Features:

  • Includes everything you need to set up your other vehicle for towing
  • Energizes the towed vehicle's power brakes through a patented process that doesn't require an electronic vacuum pump
  • No moving parts to wear out, ensuring long-term reliability
  • Uses a pilot signal from the coach's air brake system to deliver 100% direct proportional braking
  • Breakaway system protection included for enhanced safety
  • Made in the USA with a 5-Year warranty

Important Requirements:

Your motorhome must have Air Brakes to use this system. This kit is specifically designed to work with the Air Force One braking system and is not compatible with hydraulic brake systems. The Air Force One system delivers truly proportional braking that matches your coach's braking effort, providing superior control and safety when towing.

This second car kit provides the convenience of switching between multiple towed vehicles without the expense of purchasing duplicate complete braking systems, making it a cost-effective solution for RV enthusiasts who tow different vehicles for various trips.
