Has anyone with out the Tow Package bought an aftermarket receiver hitch to put on their Armada (Hidden Hitch, Draw-Tite, etc.)

I have heard the hot setup is to buy the hitch kit from Nissan. I think the reason why is the harness and other stuff is in it.

I agree with Cillyone. With the factory hitch you get the relays that you will need, a good trailer connector, proper wiring (not spliced), etc. If you get the aftermarket hitch you will need to buy the relays, etc. By the time you get it all done you will have spent about as much with the aftermarket and not have as good a system.
