I had a RBW before the B&W I THOUGHT it was a great hitch, in reality it was a POS. It clunked all the time and on my Dad's the slide bar actually broke.
The B&W is just a simple solid IMHO fool proof hitch.
I LOCK my handle closed and I attach my breakaway cable to the padlock when locking the handle. It gives me another reason not to forget locking the handle.
I personally would not leave the handle closed and drive off without it being pinned/locked just to see if it would stay closed!
I have the handle open, back into the kingpin then get out and LOCK the handle with the break away cable attached then go raise the landing gear, no pull test DONE.
