Premium Tandem Axle Aluminum I Beam Trailer Built for 18-20' Boats and Under 3,700 lbs
The COM-3700 is engineered for smaller frame but heavier boats, combining rugged durability with effortless launching. Built around a top-tier foundation from the industry’s most trusted brands, it eliminates the stress of trailering so you can focus entirely on the water.
Why Choose the COM-3700?
Elite Dexter® Component Foundation: When it comes to reliability on the highway, we don't cut corners. The COM-2900 features an all-inclusive component system from Dexter®, the undisputed leader in towing technology. This includes a heavy-duty Dexter surge actuator, high-performance disc brakes, advanced axles, and elite hubs working in perfect harmony.
Dexter Eliminator™ Torsion Axles: Bumpy roads are no match. The Dexter Eliminator™ Torsion Axles provide independent wheel suspension for an incredibly smooth ride. Even better, they bolt directly onto the frame to serve as a stiffening crossmember that vastly reduces frame flex. They also feature an industry-first removable spindle, meaning a catastrophic bearing failure or roadside accident won't leave you stranded—you can replace the spindle right on the shoulder without replacing the entire axle.
Zero-Maintenance VORTEX Hubs: Featuring a 6-year, no-maintenance enclosed grease fitting hub backed by an incredible 100,000-mile / 6-Year Warranty. Forget about messy hub maintenance for over half a decade.
Premium Dutton-Lainson® 2-Speed Winch: Loading a heavy boat requires premium hardware. We equip every trailer with a 2-speed manual winch from Dutton-Lainson®, the top manufacturer of marine winches. The dual-drive shaft system allows you to easily shift to a low gear for maximum mechanical advantage, taking the physical strain out of cranking heavy loads.
Heavyweight Upright Bunks: Standard trailers use light wood that deteriorates over time and makes the trailer float at the ramp, forcing you to fight the current. Our upright bunks are crafted from high-density, kiln-dried Loblolly Pine. Because Loblolly is a significantly harder and denser timber, it keeps the trailer firmly planted underwater for seamless, stress-free loading. And with the high density plastic molding, they can last forever.
Slick Poly Sleeves: Custom molded high density plastic is placed on top of the upright hardwood bunks and the forward target bunks. Not only does this reduce wear and tear on your bunk's carpet, it acts as a "slick" by moving water and debris away from the it's contact with the hull.
Maximum Stopping Power: The best-in-class manufacturer of marine grade disc braking is Dexter and our COMMAMDER series has it completely integrated. Demand Dexter brand for your salt water trailer.
Rust-Free Longevity: Built exclusively with stainless steel nuts and bolts to ensure your trailer joints and connections never rust or rot.
Premium Styling: Vibrant aluminum I beam, 14" aluminum wheels & rugged aluminum diamond plate fenders, sleek black/silver stylings.
Loading Assistance: 75" PVC Load Guides and adjustable target bunks make centering your boat a breeze, even in choppy boat ramps or heavy crosscurrents.
Hardware & Electrical: Marine-grade LED Plug & Play Lights (no wiring headaches) and a heavy-duty Dual Wheel Tongue Jack for easy maneuvering when unhitched.
Aluminum Crossmembers: Reduce overall weight and increase capacity.
The Tredit Advantage Program: Includes a comprehensive 2-Year Warranty alongside premium roadside and tire protection for ultimate peace of mind on the highway.
