I ended up with a B&W that I bought off this website. I was wondering the instructions say to sit the ball at 47 7/8 for my long bed I read on my last post of people sitting them at 44 to keep the trailer away from the box. I also have a tool box that sets on the bed rails will I have to take it off? what do yall have them installed at. Any information is appreciated As I dont want to cut the whole until I have good info.
