Any time you have pressure on those pins, you're going to have to pound the bejaysus out of them to get them out. Depending on why/how there is pressure on the pins, it may be easy or difficult to relieve the pressure. Hell, even some times when I'm getting back home and on a straightaway I have to pull out the rubber mallet and give it a couple of whacks to get them out.

Totally wrong. There is no reason to take a hammer to the towbar..ever. If you have an assistant, use them to slowly turn the steering wheel of the toad one way and then the other. At some point, the bar will relax and you can remove a pin. Repeat the process and you can remove the other
