I have a 2000 Tundra Access Cab V8 2x4. I purchased it with the trailer towing package that included a reciever type of hitch. I would like to know if the factory hitch is a Class III or IV? I check to see if the class was stamped on the hitch, all I found were the following numbers. 18E0 and
14317 or the right side. 18E0 and 22834990 on the left side. Any help will be appricated. Thanks.Jim W.
