Tom,
I think those big cars and their weight would push anything
around with a short wheel base. My heaviest is the 35 Buick and it only weights about 3700. That's got to be a ton less than what you pull.
I know that longer tows better but I only tow to National Tours and the rest of the year I'd like to keep the tow vehicle inside. My Silverado is 2 1/2 feet longer than my wife's old Caddy Fleetwood.(last of the big boats) It tows fine but gets filthy living outside.
Paul
