AASHTO doesn't seem to have a template for a tow truck dragging a car - the kind of wrecker that hauls off illegaly parked, broken down, or wrecked vehicles from an accident scene. For layout of an auto body shop. Any suggestions? thanks.
Check with the cab/chassis manufacturer and the wrecker hydraulics manufacturer. They can likely give you dimensions. In general, it will be the wheelbase of the truck + the length of the towed vehicle + the distance from the rear axle of the truck to the front axle of the vehicle being towed.
