Yes, I'm assuming the camper is the round plug.

The standard 7pin flat to large 7pin round (from SuperCrap etc) will work, assuming the flat is attaching to trailer, round to car.

Sounds easy, just the led trailers that need an adapter then. Cheers

As long as the trailer doesn't have electric brakes, both the adapters and LED shunt modules will work.

If the trailer has e/brakes and the vehicle doesn't have the controller then you need need to remove the wire from pin "5" of either the 7 pin large round or the 7 pin flat connector.

You can either buy the Lab products pulse busta SBA for $363 which converts the 7 pin round to 7 flat PulseBusta Busta-S-B-A

or the pawky66 module on ebay for $199 and an adapter from the auto parts store. LED trailer module Land Rover Discovery 4 Range Rover Sport Landrover D4 LR4 | eBay

For a D4, no shunt or LED "buster" box is required. Simply wire a 12V 21W globe in parallel with one of the indicator circuits (either in the trailer loom, the adaptor or on the trailer itself) . That will provide enough load for the car to recognise the attached trailer.

Cheers,
