I've been trying to find a viable solution for towing a TD with my pickup and also carrying two canoes or kayaks. Seemed that most of the racks for pickups use up the 2" receiver for the rack.
I got a Northern tool catalog the other day that has what looks like a good solution. [/url]http://www.northerntool.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=6970&productId=492929&R=492929 [/url]
With that you could use a Yakima Dry Dock or similar.
I think that will do the trick for me.
