Hi, just to provide some info for those who have the Level Best Kwikee Hydraulic jack system and would want to install a manual switching system:
Good Sam Club Open Roads Forum: any make their own leveling jack controller?
The cheapest board I found was on this site, but I am afraid to buy and do not know if the board will last: ($352)

My system is installed on a Cayman 2003. This system was mainly installed on Winnebago. Parts are still available through Power Gear distributers, cannot buy direct.
Many time I have to disconnect and reconnect the board to make it work. I did find a way to have it work, it is less intermittent now but I do not know if it will last. I connected an additionnal direct ground on to the 2 way valve, the valve on the right when looking at the hydraulic system.
