I have always been adamant about going around instead of stepping over, but for another reason. No matter how much I have chocked and stabilized, I still would not bet a leg crushing on the chance that the loads won't shift or something wont fail. Pure and simple, the coupling area is a pinch point. Never trust any of that equipment with vital parts of your anatomy. Especially when 10 seconds spent walking around the vehicle can mitigate it.
Always leave yourself an out. While you are straddling your umm a'hem... over the WD, you have no out.
Thanks for sharing and get well soon.
