The present disclosure includes an articulated coupler for attachment between a towed vehicle and a towing vehicle. The articulated coupler includes a first attachment member for attachment to the towing vehicle and a second attachment member for attachment to the towed vehicle. A ball joint member extends between the first and second attachment member. The ball joint member includes a ball at a proximal end and an elongated portion at a distal end such that the elongate portion is attachable to the first attachment member and the ball is attached to the second attachment member. The ball is retained to the second attachment member with a collar. The collar may have an aperture with an elliptical shape and a surface with a concave shape for defining a pivotal range of motion. The ball joint member may be pivotal relative to the first attachment member and may be rotatable and pivotal relative to the second attachment member.
