Thanks nohurry. Yes the truck measurements were correct. If a little nose down, a couple of inches, the slightly off parallel are not issues, and the handling is fine I guess I should follow the "If it ain't broke don't fix it principle." I could raise the L brackets a notch to make the bars more parallel. I can't remember how that affects the WD. I'll look it up and maybe try that if it seems sensible. Moving the L brackets is a whole lot easier than dealing with the head.
If you raise the L brackets, you will have to lift the bars more to get them on the brackets. That means more tension on the bars, and you'll push the nose of the truck down further. Hopefully you will not push it down further than it normally is when the trailer is unattached. 50 to 100% lift reduction is the advice I've seen.
Also if the bars are not exactly parallel to the frame, the L brackets can be tilted slightly so the bottom of the bars lie flat on the brackets. That will ensure the max resistance to sway. You can look at the bottom of the bars to see the wear pattern and whether they are lying flat on the L brackets.
My trailer is 1 to 1.5" nose down, and agree that adjusting the head is a pain.
