The owner of this 2009 Winnebago Journey stated the jack down warning light and alarm would go off when driving down the road. This Journey has a powergear leveling system but the tank is mounted horizontally. These powergear systems only have a float switch in the tank that closes when when the fluid gets low which assumes the jacks have been extended. If there is a leak or low oil level, the fluid cloud slosh back and forth while driving or turning causing the system to think the jacks are down. The fluid was not low on this so I replaced the float switch and explain it...a bit.

The lippert part number is 1510000070

I alread showed how to replace a vertical switch here :    • Replacing a Powergear leveling system...
