I would like you to check out this Safety Trailer Hitch product by Karl Pratt.
He is the inventor.
Since we JGW lovers know our vehicle can tow a house, this product would be a NO-Brainer!
I just got wind of it when I was watching the Sema Convention on new products for car/trucks on Monster Garage with my two Old Buddies!
Here is Karl's link: Safety Sentry Inc. http://safetysentryinc.com/
I'm going to get one for my Gypsy Trailer. If anyone already has one let other club members know how it's working for you.
Keep on Saving those Jeep Grand Wagoneers! YA!YA!
