I have a fifth wheel with the LCI Ground Control 3.0 system with four jacks. I was wondering if you can install a outside switch where you can control just the landing jacks. I have seen a few fifth wheels that has a up and down switch right under the front of the trailer. My control pad is inside a compartment which makes it hard to see the front jacks. I know you can buy the wireless remote but looking at maybe adding just a switch.
