Shank Length is to be so "TV" & trailer can make a tight turn w/o any part of "TV" from making contact w/ trailer.
Had a 1960 Chrysler New Yorker Wagon w/ beautiful fins that needed EXTRA shank length when towing a 1949 Yellowstone "Canned Ham." Fins made terrible holes in trailer on maiden voyage; 100 hrs to pull front skin, repair, & re-skin! 1949 YellowStone was stolen early 2003, never recovered/found.
