I have one I just pulled off of my Voyager Mini Van. This is a LARGE hitch that I had installed last year, and is rated for 3500 - 5000lb towing. Think it says something about a V-5 on it.
It's a Draw Tight. I used it twice. Once to haul my camper from Saginaw to Auburn Hills, and once to go camping last year. It has very very little rust. Cost me 210.00 installed. Willing to let it go for 75.00 obo.
