Rick, the first thing that comes to my mind as a concern is that you're pulling with a front wheel drive vehicle. Overweight in the Windstar tail could result in loss of braking and steering control on that van, especially in adverse conditions like ice or rain.
I tow my Bigfoot 17CB with a 2003 Honda Odyssey with no problems! BUT, I use a Weight
Distributing Hitch, Tekonsha P3 Brake Controller, added Transmission Cooler, Airlift 1000 airbags in the rear springs, AND an added Power Steering Cooler.
Honda manual states that the WDH, PS cooler and Tranny cooler are MANDATORY!
I weighed it out to just under the Max Gross weight
for the Honda and the Bigfoot as in the Honda Manual.
I've put about 8000 miles since I got it!
I make sure the WDH throws enough weight
forward to run level.
No problems yet, knock on wood!
First 2009 trip to Dayton Ham Radio Convention/fleamarket will be on May 17th long weekend (CDN!).
