Thanks for the replies to my previous post. I just purchased this 99 e/b 5.4l and i'm very excited about it what a beautiful vehicle. Anyways, I bought this espy with the idea of towing my 19 foot Champion bass boat. I am concerned about the tow capacity after reading some of the posts. It seems I dont have the factory tow package like i thought. The vehicle is a 2wd has a factory hitch, load leveling rear suspension and 16 inch rims, but the door panel axle reads 17, which i've learned is a 3.31 non-limited slip axle. What kind of towing ability can I expect, and what is the difference between a limited slip and non? Also where would the trans cooler be if so equipped?
