For those of you that just can't justify upwards of $2300 for a hitch set up. I am getting a Draw-Tite hitch assembly with a 2 inch reciever installed on my X5 for around $650 complete. At my reputable, local camper/recreational vehical dealer. That is less than $2300 my dealer quoted me.
I saw that someone here paid over $4000 for a dealer installed hitch assembly.
I don't know what it looks like yet on the X5 but I'll post some pix when I get it back. How bad can it be and its 1/4 the price.
