I've got an 06 dakota and need to hook it up to a trailer. Right now there is no hitch, but if I look under the back it looks like a tubular hitch w/o the receiver part. It only goes to the bumper , and I will not tow straight from the bumper. My question is, if I buy a hitch from online or u-haul, wherever, it doesn't look like i can just bolt the bitch on up there b/c of this hitch looking thing. Does anybody know what I am talking about, if not I will take pics and get back. Can i somehow hook up a 2" receiver to that "hitch" and be good, i've never seen anything like this.
