About Advanced Engineering Group (AEG)
Advanced Engineering Group, LLC — operating under their flagship brand OneMount System — is an innovative manufacturer focused exclusively on solving real-world towing challenges. Rather than selling a collection of single-purpose hitches, AEG engineered a smarter approach: a universal, interchangeable towing platform that adapts to virtually any towing scenario without requiring a separate ball mount for every job.
At the heart of AEG's lineup is the One Mount System trailer hitch ball mount — a heavy-duty universal platform that allows towing devices to be swapped out quickly and easily. Whether you're hauling a boat trailer one weekend and a livestock trailer the next, the One Mount platform lets you change between a standard ball, a pintle hook, or a clevis mount in seconds, without tools. This kind of versatility saves serious towers the cost and hassle of buying and storing multiple dedicated hitches.
AEG's ball mounts and receivers are built from solid steel and engineered with meaningful towing capacity. The OneMount Adjustable Ball Mount line covers 2-inch, 2-1/2-inch, and 3-inch receivers, and many models offer up to 19 inches of height adjustment in 1-inch increments — a critical feature for leveling mismatched vehicle and trailer combinations. With 2-inch balls rated up to 10,000 lbs. GTW and 2-5/16-inch balls rated up to 21,000 lbs. GTW on select models, AEG products are built to handle light-duty and heavy-duty applications alike.
More recently, AEG expanded their product family beyond towing with the One Step System — a hitch-mounted step that provides rear vehicle access even when hooked up to a trailer. This kind of purposeful innovation reflects the engineering-first mindset that defines everything AEG builds.
AEG products are carried by major towing retailers and recognized by towers who demand reliability, flexibility, and genuine heavy-duty performance from their equipment. If you frequently switch between different trailer types or need a ball mount that adjusts to match your rig's geometry precisely, the OneMount System is worth a close look.
