We can think of two main instances in which it would be highly advantageous to see behind you when you're at the wheel of a tow vehicle:
- When you're aligning the tow vehicle hitch with the trailer tongue
- When you're trying to see obstacles in your path before backing up
When you try to hitch the trailer and tow vehicle, you must align the two. Remember that the trailer hitch and trailer tongue are only 2 to 4 inches (5 cm to 10 cm) wide, so it may be difficult to back up the tow vehicle to blindly align the hitch and tongue. With a camera, however, this tricky task becomes easier, as does avoiding potential obstacles.
Some camera systems, such as the Swift Hitch, rely on wireless cameras that are magnetically mounted to the vehicle or trailer. Typically, the camera sends the image to a handheld receiver located in the cabin of the tow vehicle. It may transmit over a range of 300 feet (91 meters) with a night vision range of 15 feet (5 meters).
But we're not quite done with this line of tow accessories yet.
