Here's a short YouTube video on the Lippert Leveling system:
Click here.My Montana also came with a video disk on how the set up works. I think the video is too much, too fast.
It just takes a little time and repeating to get it down.
Here's how I do it. Assuming you are starting after just to hitch:
To hitch:
Push on-off button.
Push the Left and Right button at the same time.
The raises the rear jacks.
When done, you want to raise the front Jacks. Just press the Front botton and raise the landing gear (front jacks).
To lower the front jacks, press the Retract button, then the Front button.
The video explains the automated process to get the trailer back to it's original height when you unhitched. (I haven't tried that yet since my manual process works for me.)
To unhitch:
Press on the On-Off button.
Press the Front button to raise the front jacks to desired height.
Pull truck out.
Now hit Auto Level and wait till the green light in the middle is on.
Here's the link to the "Level-Up" owners manual in PDF form also. I found this helpful, but also a lot of information that I haven't absorbed yet:
