2007 Lexus ES350 towing.

I am trying to tow a motorcycle and the drive is about 3 hours. The U-Haul motorcycle trailer weighs about 1000lbs and the motorcycle is about 470lbs. I understand the rating for the ES is 1000lbs but this seems to be really low for a V6. Does anyone have experience with towing or know if it’s okay to tow it?
