Thanks to those that gave positive feed back.. I figured that's what I did WRONG, raised it a smidgen to high. I get the manual out each time and follow thru the procedure both for hitching & unhitching.
I try & do as mileshuff said:
When hitching set the kingpin just slightly below the level of the hitch plate and let it ride up. Front of capture plate just at the bend in the hitch.
Unhitching the 1/2 dozen times I've done it, I try & only raise the trailer until I just barely see a gap, maybe 32nd to a 1/16".....maybe it was to high, will lower it from now on,
Guess I'm one that's not smart enough to follow direction.
Thanks again
Milo
