Did you ask them for the exact part-number of this valve ?
Did you ask them what's entailed (the procedure) in having the valve "adjusted properly" ?
Me, I'd want the exact part number (to see if it indicated a revision) ...... and at least a look at (if not a copy of) the procedure used to adjust it.
Who's the dealer that performed the work, and in what city/state are they located ?
Hmmm ....
Not to put to fine a point on it, but it would probably be a lot "hotter" topic, if you could provide some info that would actually be
useful for others to achieve the same result.
Say, something like the actual p/n's and procedure used ...
There was one thing I found very interesting at the end of your video, in light of your thread and the totality of your comments in regards to this matter:
"..... but I'm sure even this auger being six feet out is waaay smoother than any other L3800 hitch out there ......"
Really ?
Why ?
