I'm looking at getting an adjustable height hitch for my 2017. As I'm sure you know, it has a 3" receiver with sleeves for 2.5" and 2" hitches. My vehicle configuration is rated for 15,000 lbs conventional towing, which I think a 2" shank can handle. My question for you is, though, is it worth getting a larger shank? The cost isn't that much different and I wouldn't have to mess with the sleeves. What am I not thinking about?
