Lippert Level Up Question

[flyfishing48]

Ok, with the 6 point level up, you can press the left and right button to return to the height the camper was at when auto level was initialized. ( the unhook position ).
I have only had the oppurtunity to do this twice, but it looks like only the front kicks are adjusting. The other 4 appear to remain in the same position. Both times that I did this the front was raised to get to the right position and the rear jacks just took on more weight. Is this how it is supposed to work ? I guess I was expecting the other 4 to retract.

Another feature you may not know about is the "return to unhook position" will only work if the trailer has to move up. If it needs to move down to reach the unhooked position, it will not work and you will get a message that says "feature disabled". I guess this is a safety feature to prevent the trailer from coming down on something while it is unattended.

Either I didn't know that or I forgot it. Either way thanks for the tip.

The 2 rearmost (intermediate & rear) jacks on each side share a common hydraulic source - that ensures they're loaded equally. Watch them come down when you start leveling - the one closest to the pump (the intermediate jack) will usually start dropping first, followed by the rear jack. By sharing a common hydraulic supply, the intermediate and rear jack on a given side are self-compensating - if the front of the 5th wheel is raised, the rear jack (being just behind the wheels) will compress only slightly, and the intermediate jack (being in front of the wheels) will extend slightly, keeping the pressure between the 2 jacks balanced. That's why there's no "intermediate" button - just front and rear jacks, and the intermediate jacks are part of the rear jack system.

No, you have nothing to worry about when returning the 5th wheel to the "unhitch" position.

This was helpful. I think I get whats going on now.
Thanks

Thanks for the explanation. For this scenario to happen, wouldn't the valves for each jack have to open when the front are activated? I didn't watch real close, and the amount the front had to go wasn't very much, so what you described could happen with out my perceiving the movement of the other 4 jacks.
So sounds like I have nothing to worry about.

[RustyJC]

Bear in mind that the hydraulic pressure is constant in the 2 rear jacks on each side. Therefore as the front jacks extend, the rearmost jacks will retract with that fluid being directed to the intermediate jacks which will extend, but none of the rear jacks will ever have more pressure than its corresponding intermediate jack.

The rear jacks won't retract until you manually retract them or select the auto-retract all jacks function on the keypad once you're hitched up.
