Thanks for the input. I hope to load up and hit the scales tomorrow. But as requested I took some time to take some measurements. I will admit I deviated from the owners manual a bit but I think the readings still tell enough.
The manual says to drive 2 miles with the weight distribution (WD) unhooked. Then do the WD adjustments. Well I did not drive the 2 miles, I just left the key off so the autolevel would not function.
Measuring from a fender to the ground can be fraught with errors as the tape can land in different places on the truck as well as the ground. So I took some masking tape and tried to ensure consistency.
To keep it straight the tape measure goes between the lines.

And here's the street.


I added one spacer washer that seemed the same thickness as the others and it put too much back on the front. So I went back to the garage and found a thinner washer. It looks like I still added a bit too much to the front by 1/8", but I'm not sure if I can get it better than that. I guess I could try replacing an Equal-i-zer washer with another thinner washer. But that will only change the thickness by .39 mm. The washer thicknesses are at the bottom of the spreadsheet below. I now have 5 equal-i-zer washers, the one thinner washer, and one washer that I did not measure.
And the bars are parallel.


Edit: After looking at the numbers again I think replacing an Equal-i-zer washer with a second thin washer will put me right back at original height. Now let's see what the scale shows.
