Good morning, posted this in the Phoenix forum, but thought I'd see what you guys thought as well. Have a new boat, and the coupler goes on great, but does not always want to come off. The folks in the Phoenix forum told me I should pull forward after backing in to release a little pressure, and grease the ball. Actually, I'm gonna get a new ball. That's probably enough, but wanted to see if anyone had any similar experiences and/or cures before picking up the boat again.
