Chiming in as someone with a 1H BP McBride, my first and only trailer. I love it’s affordability (I have less than $5k into it right now) and the fact that it’s narrower than what I tow with, which means I have better visibility around the sides of the trailer in the sideview mirrors.
If I ever added to the herd it may no longer suit our needs (as someone with a preference for draft crosses…), but for now, it does the job!
