Genright (
This) or Savvy (
This) are probably your best bet. Going to be a bit hard to find a completely flush bumper with a hitch included. A hitch will take away a good bit of departure angle so many companies choose not to include them on their bumpers. From what I understand, the Savvy bumper isn't really supposed to be used for towing. The receiver is more for recovery than anything else. There are definitely bumpers that include receivers, but they might not be completely flush like the genright kit above.
