Seems to be two conflcting approaches....one says air up the bags before engaging the WDH and one says air up after engaging the WDH..
Any other thoughts?
You wont find anything but opinions to air up before applying the WDH, and you asked the right questions challenging this. It is simply not logical to lift the rear prior to applying the WDH.
All formal instruction will tell you to air up (or turn on auto-level) after WDH is applied. Its just not easy to find online. The link to eTrailer previously posted is a good start.
