I know these are the recommended pin, but I've already lost one of these, and I noticed another one had not snapped down tight the other day. I think they get dirty and the ring doesn't necessarily snap flush and because they are top heavy they roll down and just fall out. I'm partly to to blame for not checking well, I agree, but I like things to be a little more passive. I think I will just go straight to the padlock. At least on a padlock, even open it would stay in the pin.
I don't know that brake system he was using that well, but I am somewhat comforted that on my RVI2 I can manually apply the brakes on the toad and hopefully avoid the back slam. Not that I want to test my theory :), but I think it would work.
