locking up fifth wheel

Hi all
Bit of advice please, I am not sure of the make of my coupling, it looks like a Curt but I bought it SH with no plate. It has two levers in what can only be described as "keyholes" at the front which lock the coupling from moving in the left right plane, I have always left the coupling unlocked, but wonder what is the reason to lock it? I have a Rockwood ultralite fitted with a revolution hitch, any advice or comments welcome,
Thanks from across the pond in England

Sounds like you have a RBW Industries "Little Rocker" hitch. The levers you ask about lock out the side to side swivel of the head. I guess some owners wanted to lock out the swivel head if they encounter trailer sway as when big trucks pass on the interstate. See pages 8 & 9 below.

thanks for that, big trucks don't have a side to side movement, I thought the side to side movement was for crossing uneven ground without putting a strain on the trailer, but still not sure of the advantage of locking the movement, I will lock it for highway use and see if it makes a difference, I seem to think it may have just been a marketing ploy?

I would leave it unlocked. Better ride and easier to hookup. I changed out a fixed hitch for a rocker. Much better.

thanks, that seems to be the good advice and the majority appear to agree
