Yoke couplers are not a mystery. Their function is simple. I've seen many a stock coupler at Escape rallies, that function smoothly and easily. Mine was not one of them. All the lubing, adjustment, and unhooking techniques with the tow vehicle were to no avail. It was just a stubborn and defective coupler, that's all. The collar locking coupler in contrast has been trouble free. If you have no issues with your stock coupler, great! But that experience should not be used to imply a lack of knowledge or technique on the part of others.
