Jack Grounding

[R2D2]

Hi all,

We have just traveled through the south to Orlando and with all the lightning something came to mind. I have, but don't usually use plastic pads under the jacks. We usually set up on concrete/asphalt pads so I didn't think they were necessary. However, is this a mistake? Do they become a ground for the motorhome and if so, is that a problem?

Look forward to your thoughts.

Thanks,

Fred
