Ford Explorer Forum : “What is the hitch class on this vehicle?”

class 3

not all are class 3, some are 2

you can actually use any class hitch even class 2, or 3, but the only difference is between the weight being towed, if you are towing a big boat you can't use class 2, you must use class 3, and then be careful of tongue weight, how much the actual tongue can pull.

you can look in a few places driver side door panel may have the info on the receiver, or check the Manuel
