If you tow more than one trailer -- a fifth-wheel adapter, a boat, a car trailer, a utility trailer -- you already know the hassle of digging through the truck bed for the right hitch ball every time you hitch up. The B&W BMTT31004 Triple Tow Ball Mount puts three pre-mounted tow balls on a single heavy-duty steel shank. Pull into camp, flip to the right ball, pin it, and go. Built to B&W's commercial-grade standards with the kind of fit and finish RV towers and gooseneck haulers expect from this brand.
The BMTT31004 is part of B&W's Tow & Stow / Triple Ball lineup -- a category B&W developed specifically for towers who regularly switch between trailers of different sizes. Instead of carrying a bag of loose hitch balls or a multi-step adjustable mount, you get three fixed balls permanently positioned on a rotating or multi-position head, all on a single 2-inch receiver shank.
At 18.55 lbs, this is a substantial, all-steel unit -- not a lightweight import casting. The weight reflects the solid steel ball mount body and the three installed hitch balls, which are forged steel just like you'd buy separately. The overall envelope of 12.0 x 7.83 x 4.75 inches keeps it compact enough to store in a truck bed toolbox when not in use.
Typically covers 1-7/8 inch, 2 inch, and 2-5/16 inch ball sizes -- the three most common trailer coupler sizes in RV and trailer towing. No loose balls to lose.
Fits standard 2-inch Class III and Class IV trailer hitches found on most full-size trucks, SUVs, and tow vehicles used with RV trailers.
Forged and machined steel body and ball assemblies. Finished with a durable powder coat or black oxide -- built to B&W's working-truck standards, not recreational-only spec.
Rotate or reposition to the correct ball for your trailer coupler without removing the entire mount from the receiver. Cuts hitch-up time significantly at a busy campground or job site.
The BMTT31004 is the right choice if you regularly tow two or more different trailers -- for example, a 2-5/16 inch gooseneck-style RV trailer plus a 2-inch utility trailer plus a 1-7/8 inch single-axle boat trailer. It's also popular with RV owners who tow a car dolly behind a motorhome (using a tow bar receiver adapter) and need a secondary tow ball on the flat-tow vehicle.
Campground hosts, RV park operators, and mobile RV service techs who move multiple trailers around a property find the triple-ball format especially practical -- no toolbox full of loose balls and wrenches required.
This mount installs into any standard 2-inch (Class III or Class IV) receiver hitch tube. It secures with a standard hitch pin and clip or a receiver lock (sold separately). It does NOT fit 1-1/4 inch (Class I/II) receivers or 2-1/2 inch (Class V) receivers without an adapter.
At 18.55 lbs and 12.0 x 7.83 x 4.75 inches, the BMTT31004 stores easily in a truck bed toolbox, a basement compartment on a Class A motorhome, or a cargo area. The three installed balls do create some awkward contact points -- a foam sleeve or old towel wrapped around the assembly protects truck bed liners and nearby gear.
