ABSTRACT Method and apparatus for use with a trailer A method of coupling a trailer to a towing vehicle comprising the steps of: mounting a hitch on the towing vehicle by way of a strain measuring device adapted to provide a vertical loading signal output representing at least vertical loading applied to the hitch connecting the trailer to the towing vehicle hitch by way of a complementary hitch on the trailer; processing the signal output and displaying the result to enable at least the load vertical loading applied to the hitch by the complementary hitch to be identified and in the event the size of the load lies outside an acceptable range then adjusting weight distribution in the trailer to bring the value within the range. A device for a towing vehicle either for forming a part of a towing hitch or for location between the hitch and the remainder of the vehicle, the device incorporating: a transducer, such as a strain gauge, for providing a vertical loading signal representing at vertical loadings applied to the hitch and a processor for receiving the loading signal and thereafter providing an output signal representing the loading applied to the hitch. The device can be used to generate a number of other signals (such as signals relating to towing vehicle or trailer geometry which, separately or in combination, can be displayed to inform the driver of the towing vehicle of the static or dynamic state of the towing combination or of motion of the trailer relative to the towing vehicle. In addition such information can be used by the device to generate control signals such for operating the brakes of the trailer to provide for safe operation.
