Looking for a Fifth Wheel hitch with single, wrap around jaw

I have an RBW hitch, now on it's third truck, that has a straight, slide across bar. Very safe and foolproof, if the bar is across it is locked. The problem is the bulk of the weight is against the single flat bar, resulting in wear the slack.

I am getting ready to retire and do some serious travel. I don't want a split jaw hitch where I have to pull test every hook-up to see if the split jaws are locked. It seems like I have seen fifth wheel hitches with a single forged jaw that wraps around the pin when it closes.

Any suggestions and experiences? Thanks
