Just recently coming back from a show we were loading my big 17hh ottb and he was convinced that he wouldn’t fit in the trailer. So he was a bit stressed and in all that he hits his head twice, thank goodness he was fine the rest of the way back home. It might have sounded a lot worse than how much it actually might have hurt. I was pretty upset about it though.
So I am seriously considering getting a head bumper, but do they offer a good amount of protection ?
