2004 crescendo 8356 hydrolic leveling jacks

[Silent Thunder]

One of my jacks is broken as in the leg is totally missing (bought the home that way). My dealer said the factory original jack system is no longer available so I need a new system. What make is the original unit from the factory and can one jack be purchased even another brand and used in my system?

The system in my 06 Crescendo is a power gear system. If you have the same,
the jacks are available.
One example:

Attached is the manual and a parts list for the Power Gear system. Hope it helps.
