2026 B & W Trailer Hitches Rail-Mounted Fifth Wheel Hitches RVK3550

You have rails? We can fit them.

Our rail-mounted hitches fit industry standard rails.  Pin the base in the rails, then set the coupler on the upright arms.

Our handle works, even in a bind

The handle operates effortlessly and never leaves you in a bind, thanks to the use of a cam.  When the handle is open, the cam moves out of the way allowing the jaws to open when you pull away and uncouple.  When the handle is closed, the cam prevents the jaws from opening, preventing accidental release.

You might forget you're towing

We set out to build a hitch with the smoothest ride in the industry.  Our jaws are machined to precisely fit your coupler, so there isn't room for sloppiness.  A spring allows side-to-side movement without slamming.  And the whole coupler rides on polyurethane bushings that absorb roughness from the road.

Clearance for your cab and bed sides is built in

A series of holes in the base gives you both height and distance adjustability.  Switching the slanted arms from one side to the other increases the distance.
