Thanks for the advice folks. I think I'm going to have to get the trailer back out of storage this spring and do a bit more closer inspection on the king pin and hitch, and possibly take it in to the dealer. Hopefully its a minor adjustment as some have mentioned.
My hitch has the manual slider bars. I could see how any loose play might cause this jerking problem if the upper hitch assembly is not held securely when locked in the tow position. This will also be on my list of things to inspect.
As for the weight distribution...what I recall from last year is that I experienced this both loaded and unloaded. That's not to say my loaded weight is all right. I'll have to get to the scales this spring as well.
I did plan to start greasing the king pin a little this year. Each pivot you make with the trailer and TV puts a lot of wear and friction on the circumference of the pin and hitch jaw. Does anyone have any grease recommendations to use?
I will update everyone when I find out more details. Thanks!
