Reversing your vehicle onto a trailer, caravan or horse float can be a tricky business, and even with the often dubious assistance of an outside observer, chipped bumpers and the odd expletive are not out of the ordinary. A remarkably sensible solution is now available in the form of the TowChek, an onboard camera system from Donnelly Corporation that gives the driver an extra set of eyes covering the approach to the tow-ball.The TowChek system consists of a CMOS video camera mounted on the rear of the vehicle with a wide enough field of view to include both the tow-ball mount and the approach to the tongue of the trailer.

The TowChek retails for US$449 and is available online at
