I posted this on the Tow Vehicle Forum, but probably should have posted it here instead.

I finally got a truck. A cordial thank-you to all who offered suggestions. It's a 2018 Ram 3500 crew-cab Turbo-diesel dually with the Aisin transmission. Stated towing capacity is about 25,000 lbs. So now I need to get a hitch. What do you towing gurus recommend? I have been offered a B&W Companion hitch purchased by someone who never actually put it on his truck or used it for $750. Would that work, and is it a good deal?
