I am getting to redo my setup after getting a different tow vehicle,noticed the washers and the button bolt or whatever it is is loose, is this normal? It is not mounted on the truck but I thought it was a bolt?
Not normal. When you move it to the new truck make sure all is tight. On mine (and I think it's in the manual) I left the big side bolts loose and hitched the trailer including the WD bars. Raised the tongue jack so all the weight was on the hitch. This put all the pressure on the washers. Then tightened the 5/8 inch bolt on the bottom of the head and tightened the large side bolts.
Eventually I'll probably have to do this again, but so far it's been tight for a few years.
