Dropped 5er with Pullrite SuperGlide?

Haven't drop it yet...knock on Pinocc's head. After pulling TT's for over 30 yrs we switched to a 5er. I practiced hitching & unhitching in the driveway maybe 25 times so I had an idea of what I was doing when it came time out in the wild. Well on our 2nd trip while trying to hitch back up after out camping in a FSCG, the truck was on a slight side to side slant and also a front to back slant. Took 3 or 4 tries to hook it up but finally got it. Did pull test... thought all was good. Got home & couldn't get it unhooked. Pulled handle, jaws wouldn't open. Had to do some prying and the little lever under the jaws just fell off. Jaws opened and finally got it unhitched after some work.
When I hitch I bent the lever that pivots under the jaws and it wedged the pin in there with the jaws around the pin. Was lucky we didn't drop it on the way home. Had to call Pullrite & get them to send me a new lever. Also left the jaws open while unhitched, Now each time after unhitching I close the jaws and reopen em before I hitch op again & make sure .... I really make sure everything is totally lined up & the pin is exactly where it is suppose to be on the hitch when backing up to the pin. May take me a few extra minutes but could save me some bucks.
