Can we talk about Stock Trailers?

[QUOTE=Bluey;8584151]
The true cowboy stock trailers are half tops, so you can rope and pull one in if you have to haul it and no place to load it, like at least a good fence corner you can pull along and drive it between the trailer and fence and they hop in there.
With the half top, you can keep pulling the critter in there, let the horse holding it and run around and close the back gate.[/QUOTE]

I’ve seen the half top trailers before but never could figure out why someone would design a trailer that way. Thank you for the explanation.
