I have a Chey 4 door 3500 heavy duty which has a very high bed. The B&W has bolt adjustments to raise the hight of the hitch plate. before you purchase have the dealer adjust the hitch to the hightest setting and test your trailer. I love my hitch, being a disabled person the hitch is 2 parts so I can remove the hitch myself, Also it has no rails to get in the way of the truck bed. As they are very easy to remove I have a 6 foot cable locked to the bed then to one of the upper mount pins.
