I used the factory tow hitch, I was sketchy at first... but it help up well for the 3 years I owned it.... I was towing about 6 times a week....
I picked up the the OEM wiring harness kit from Land Rover for about $140.00 and installed it myself, really simple...
I actually miss that SUV. It was perfect... I beat it to heck.. Towing all the time, Off roading all winter, snow adventures, being dumb and young with it.. LOL.. I miss it.
Now i'm looking at an AWD Audi SUV.. *drooooooooool*
