I am thinking of getting a Popup tent trailer and travelling around the States this summer. I have a Disco II which has a steel square towing recepticle, I assume to latch in a ball which the trailer can connect to. I don't see any wiring harness near by. Do I need to buy a ' tow wiring harness' and if so where does it wire into the Disco?
And does anyone know with any of the wires that do go to the trailer, can I charge an external 12 v battery (deep cycle RV type) off this?
Cheers,
