Trailer hitch and harness

[hinten]

I checked out the official Hummer website. The 'biggest' drop hitch that Hummer sells is 5 1/4" so I figure somewhere between 5 and 6 inches I'll be alright.

Thanks for the clarification of how the brakes work. I was just wondering about the letter that hummer send out regarding the trailor brakes coming on when you turn on the lights (!).
