Not having an auto leveller, I use the JW for front to rear levelling. After that, it just stays there all ready for when we depart.

In that lies the pertinent point, you have not "auto levelling", so you use the JW to level the van, so it is still in the right position even after the steadies are set.
There can be a whole different situation with auto levelling, where unless you first level the van with the JW before, using the Auto levelling the JW could end up dangling in space or left carrying the bulk of the front load with the van unnecessarily up on stilts. The JW is dictating the van height if left too extended.
With Auto levelling its best to lower the nose before you implement auto levelling, that way the van will not totter on over extended steadies just to live with where the JW had been.
I have the verbal capable, steady deployment system, only deployed after I set the and pass off the levelling as adequate .
That way, by default the JW is down, because that was where it needed to be to level the van.
