Still no video, so I wrote to Lippert, not much help there either, but looking at the PDF owners manual I found this......
Manual Mode: Scroll to "MANUAL MODE" (Fig. 2G) and press "ENTER" button to start Manual
Level operation.
Jacks operate in pairs. Use "RETRACT" or "EXTEND" to operate front jacks, right
rear and left rear jacks.
Notice the bold underline....Jacks operate in pairs! So you can't move them independently!!??
Really?
