The B&W Turn Over Ball set up is a very common hitch...and well loved by it's many owners...I had about $1250 in my Turnover Ball and Companion Combo when I installed the Turnover Ball in the last Ford in 2010...Current Chevy had a Young's Welding Pop Up System installed so I just bought their Companion adapter...You are looking at their slider which is more expensive and only was introduced last Fall...IMO, if you can get it installed for what Tweety's will just sell the equipment...hard to beat that price...
B&W is an American company manufacturing a very high quality product that they stand behind completely...the owners of their products are almost unanimous in their support...
