First, I could not find a way to search in this forum so I will just ask the question in the forum. As I understand it, 2016 and older HiHys use only the 67 hp rear electric motor for reverse and it has a pretty short duty cycle. That might be a problem for me when backing a trailer on muddy ground. Even with the tongue weight, the front wheels would have more weight on them and therefore more traction. And, of course, awd in reverse would be best. Are the 2017-2019 models like that, too?
