Slides and Ignition
I also have a 2016 Palazzo and the slide switches are locked out whenever the engine is running. I do the same sequence mentioned above:
1. Pull into site
2. Unhook toad
3. Dump air bags
4. Drop levelers
5. Hook up power, water and sewer
6. Turn off engine
7. Move slides out
This was before the change to the Firefly control system so it may be possible they changed the slide lockout.
