I have been using a Q5 20k for abt 2 years now. It works very well once you figure it out. Mine is very picky about final latching. I figured out if you don't go into it exactly straight it won't latch all the way. My solution is back into it until it starts to latch. Then I raise the landing gear to just off the ground and let the rv center in the hitch. Then I raise it back up and it latches very easily.
I always do a visual check of the jaws but with the system they have it's not really necessary, just cautious.
