Thanks guys, sounds like it should be strait forward then.

When buying one of the brake controllers what do I ask for? Do the connections differ from car to car? I just emailed etrailer and they came back with "we have nothing for the Discovery 5" yet I see others have gotten stuff to work.

As for wireless, working in the wireless industry I have yet to see anybody guarantee 100% uptime. That scares me a bit with brakes.

 

There is a plug under the dash for the brake controller. Uses some harness as my LR3 did and Ford vehicles.

 

Question regarding what hitch people use for towing with the DV. I came across the below in the online Digital Handbook for the 2018 Discovery(Towing - Tow Hitch). I can't find any hitches on eTrailer that meet the recommended length of 6.5". And for the camper (delivery in June)I am planning to tow I would need a hitch riser. Wondering what others have done regarding a hitch for a DV? Any issues using a hitch riser ~4." Thanks!

The fitting of a tow hitch is required for towing with the class IV tow hitch receiver.

The following tow hitch dimensions must be adhered to:

1. The maximum recommended length is 6.5 in (165 mm).
   
2. The maximum recommended ball height is 1 in (25 mm).
3. If required, consult a retailer/authorized repairer for the latest information.
