Does It Matter Which Orientation You Install The Curt Lube Plate 16721 ?

Question:

In reviewing your QandA for the Curt Lube Plate 16721, I see two different answers to the question of if there is a top/bottom of the plate. One says yes, that the side with the sticker should go against the kingpin. The other said it does not matter. There is nothing printed on the plate. Which answer is correct?

Hey Tom, the Curt Lube Plate for 5th Wheel Trailer Hitches - 10" Diameter # 16721 doesn't have a top or bottom; it just installs in either orientation. I see the Q&A that says otherwise, and I'm correcting it now so there's no more confusion. Sorry about that!

What kind of truck and trailer do you have?
