Uh well no you couldn't but I can't think of a reason to load a horse through a fence to be honest. I really don't see the problem if one doesn't like a certain type trailer one shouldn't buy it.
And neither could I. I was using that example to show what point we were talking about.
There is no problem. The OP asked for opinions on different types, "if you don't like it don't buy it" is something every smart person does and is not why this discussion was started.
