ABSTRACT:
A tow-bar adapter for towing a loaded trailer behind a combat vehicle permits opening of a rear ramp door on the vehicle and supporting the open door on the adapter as the vehicle proceeds forward. Longitudinal legs each have first ends provided with a lateral bore axially aligned with each other. Pins extend through each lateral bore and through bosses mounted on the vehicle, allowing rotational movement of the legs about the pins. Cross members extend between and are connected to the legs and a caster assembly is connected to the cross members to provide vertical support for the tow-bar adapter and any carried load. A towing pintle on a cross member connects to a trailer, and the caster assembly rotates about a vertical axis to allow the tow-bar adapter to slew and follow along behind the vehicle as it turns.
