This is a plate a created (very basic), for the Lippert Ground Control 3.0 auto level system for our camper. Since the back is exposed to the propane tank area, there's a chance water could splash up into the panel and cause a short. I came up with this to mount onto the back and prevent that. I'm using 3M Command Velcro Strips to hold it in place (so that it's removable if I need to work on the panel). There's a hole in the back that lets the wire go through to plug into the panel. I'm waiting on a grommet from Amazon to plug in there, to help with waterproofing.
It fits over the whole panel, so that it's flush against the side of the camper. I've since started adding a 5/8" grommet, and it helps seal the back of the plate even more.
