I have the Anderson steel version. I have had it on two different 5ver toy haulers with no issues. 16400 GVWR and 18000 on my current trailer. This hitch works incredibly well. I ditched my 150lb+ slider hitch and will never go back. I can hookup and unhitch at any angle making it very nice when unhooking during camping. So easy to hitch up knowing the ball is inside the receiver and no issue of wondering if your lock bar captured the king pin or not. It also rides better going down the road than any of my friends even with their air boxes. Since the trailer articulates on a ball there is freedom in all directions.
Some people are just afraid of change. Anderson designed this and stands behind the product with a 20k rating. Far superior in every aspect IMO.
