Are you trying to tow using the step bumper? If so, you are limited to a
3500# trailer and a 350# tonque load.
I suggest you read the Nissan Towing Guide (see
formatting link
). If you are going to tow a lot, I'd suggest getting a receiver hitch like the one Nissan sells as part of the trailer towing package (see
formatting link
). Your goal is to have the trailer as level as possible when towing. I'd guess the ball with the least shank that still allows the trailer hitch to clear the bumper under all conditions is the one you want (unless the log splitter is unusually high).
