Funny this popped back up...
While I was at storage earlier this month I decided to video what mine does.
At the start of the video the legs are at full extension, all the way up and you can see as I drop it down that the left side of the camper moves first. I run it all the way down and then start back up. On the way back up I stop part of the way to drop it back down, simulating raising the trailer to unhook and then adjusting up or down. After that I take it back to full extension and you can see one side gets there first.
