I have a 2021 Tradesman with the prepackaged puck system. I bought the curt a16 hitch and when I lock the pucks in place it is easy to do. I was told there must be some resistance and I needed to tighten them up. We’ll on the crown nut where the cotter pin slides through I moved it one slot and it had a lot of resistance but I was able to use my hand to tap it in the lock position. Is it better to have that much resistance or to have it easy to lock ? I’m not familiar with this style of hitch.
