Another +1 for B&W - a Local company to me -
I went with the B&W Turnover ball goosneck, and the B&W Companion 20K slider hitch.
This way, I have a usable Truck bed when not towing, I have an option to run hay wagons on the farm with a goose neck, and I can (within 10 mins) slot up the 5'er base and head and hook up to our 38FLSA easily.
No high pinning is possible with the B&W, the way the jaws work it wont let you lock it down.
All in, I'm at 1700 installed for the complete set-up.
