I run my electric driven front landing gear down a few inches before lowering the inner drop down portion......how much depends on levelness of site.
I prefer to NOT have much of the inner portion extended any more then needed.
After raising 5vr enough to unhitch and drive truck out I level 5vr front to rear using front landing gear legs...then drop front down 1" off level.
I then set up rear stabilizers and check they are snug
Then run front back up to level
You talk about rear stabilizers having an outer and inner sleeves so you must have '4 point leveling' system
Set up front level then set up rear level.....dropping that onner sleeve as little as can be done and still have enough range with outer driven sleeve.
After a few times you will get the idea what/how much based on levelness of site.
Just remember this
Wheel chocks........1st thing ON before unhitching and Last thing removed after hitching---even when on flat surfaces
