Hidden Hitch and Draw Tite both offer class V hitches. This is what you are looking for.
Most class v's will allow you to pull up to 10,000 lbs w/ weight distribution. (IIRC...check to make sure) check out www.hiddenhitch.com
for more info. Southgate hitch and plow....and I'm sure Monroe Truck accessories sell these.
I run a tekonsha brake control on my dad's van. I am VERY happy with it. It's not the prodigy, but they make a good product overall
