Carries on creakily
Indeed, like this . This design of welded in fixed breast bar should be banned.I've seen them climb on top of tack lockers which is close I'd imagine. The trailer ones undo from the outside with an allan key because while not every day it's common enough you have to plan for it. That's why I'm really put off one that have a solid half wall for their heads to go over - no way you can take that down when they are stuck over the top. Some really well regarded makes have that which I really don't understand.
I've only hired a stallion box, I don't own one, but all 3 neds (who travelled on separate occasions, not all at once!) travelled very well in it.
