I have the Black Widow dual. I've used it for thousands of miles on a weak Chevy Traverse. I dont have anywhere to store a trailer and i dont like trucks. I can carry iur bikes easily and remove it in 2 minutes to store on the side if the house. Its so convenient. I stiffened the rear suspension with $15 inserts. https://a.co/d/04hGmJFz
