Had an issue this past weekend and just looking to see if this might be a common issue or not. Below is my post on the Forest River forum.
We went on our 2nd trip with the new Crusader this past weekend and the rear jacks would not move. I obviously tried manual mode to no avail, I called Lippert and they didn't have any suggestions.
The "rear" button lights up on the control panel when I press the button so the panel is working. I am assuming they are not getting power since neither rear jack would respond. I doubt both jacks would go out so quickly. Front jacks worked fine.
I have an appointment in a couple of weeks to get it to the shop but I was wondering if anyone had any suggestions where I could start looking? Maybe there are typical problems I could look into.
