has anyone used or use a B & W stow and tow hitch? saw this on an outdoor channel this morning, I have trailers with varying receiver heights and multiple receivers, looked up specs on this but was hoping for first hand experience or opinions. I have my shop trailer which most of the time is hauling lawn and garden equipment, a 28' fiberglass boat and a 27' enclosed cargo express trailer that is steel framed that I haul 3 to 4 sleds in at a time. My question is do you feel having the lack of solid connection on the drop part of receiver ( meaning by moving pins you can change height of receiver ) is strong enough to haul these trailers without worry? instead of a welded connection with one pin you essentially between the ball, adjustable height and the receiver itself there are 4 pins which seems like a lot of non solid links pulling on a lot of weight, opinions?
