This is my procedure which very much limits problems of the site being unlevel.
Level side to side by placing Lynx leveling blocks under low side wheels (optional as necessary by site)
Chock wheels (mandatory every before unhitching the TT fronm TV
Disconnect WDH
Level front to back with tongue jack
lower stabilizer jacks
I have this procedure down to a science before any family member gets out of the TV. Takes <5 min usually which is beneficial as some campsites I have to block the campground loop road traffic until unhitched. When leaving, TV hookup is last. Patio mat put away, awning in, hitch up, grab chocks and blocks, leave. Last steps with minimal road blocking time.
Since I have perfected this procedure with my current equipment, I have little excuse not to do this all the time, even under circumstances of quick overnight stops along the travel route.
