How much can a 1993 Mercury Grand Marquis tow?

i have the same car...i tow a 2000 lb boat with it with no problem..been doin some research and my book says it will pull up to 5000lbs..im looking at a camping trailer that weighs almost 4000lbs and i m pretty sure im goin to buy it with no towing concerns at all..i would say just dont go over 5000lbs unless you beef up the suspention and get a transmission cooler installed..good luck...and drive her slow and careful...dont be in a hurry and leave some distance between you and the car in front...hope this helps...kev.
