Now there is a good question. All of our past RVs had individual switches for each slide out. Of course all of the past slide outs have also been electric powered.
With our new Wildcat the bedroom slide is electric and on it's own switch. However the opposing slides in the main level of the trailer are hydraulic and extend one side at time but on the same switch.
I would be nice if there was a switch allowing or a choice to open one or the other independently.
