When I press the tow/haul button on the 2023 Tundra I have two options to choose from. 1) Tow/Haul or 2) Tow+. I've looked online and even the the truck manual and I cannot find it addressed anywhere. Forgive my ignorance, but can someone please enlighten me as to the difference between the two and under what circumstances each should be used. Thanks in advance.
