Trailer Hitch Ratings

I am planning on moving in the fall of this coming year. I want to rent a U-Haul Trailer. I have a 2012 Nissan Frontier. I don't Have a Trailer Hitch yet. I was wondering what rating I would need to tow that.

depends on the tongue weight and how much you can going to put in the trailer, they will probably want a class 3 or 4 if you are going to tow much. if total weight is under 3500 pounds they might let you use a class 2
