Towed vehicle with a winch- how can I do this?

I am the new owner of a 396XL and I want to tow a Jeep Wrangler. I live very near Roadmaster so I called them up and they told me that they do not make a plate for a Jeep which has either modified bumpers or a winch on the front.

I have yet to buy my Jeep but was really thinking of having a winch on the front. Are there any tow bars that allow for this with the vehicle towed with 4 wheels down or will I need to get a dolly or trailer for this???

Also, any recommendations on your favorite (or best) towed vehicle auxiliary braking system?

Thanks

Dave
