I currently run a turnover ball and B&W companion on my 2007.5 shortbed crew cab. I have not had any issues but I am very mindful where I am and where I am going. If you are thinking you would like a slider, B&W just released a manual sliding Companion that is designed for us short bed folks. If I replace my hitch it will be for the Companion slider but I do not see that happening anytime soon. There are a lot of Companion owners/lovers on here so I am sure you will get more responses. Oh and I did not install, it was included with the truck when I bought it, Companion and all. Very glad it was too. But I think there are some things better left to people who do it for a living so I would have it installed.
