digital volt meter
Can I disconnect the wires for the battery on the back of the fresh/black/grey/battery meter in the camper and install this digital meter instead? https://www.amazon.com/DROK-DC2-5-30V-Waterproof-V...

How would you mount it on the tank display panel?
I've mounted similar ones by using a standard single gang blank outlet box cover plate and cutting a square hole using a utility knife (drill a few holes to get the cuts started). A nylon cover plate is softer and easier to cut a hole in it. Then you can just screw the plate directly to a wall - you don't need a box behind it because it's low voltage.
You could mount the meter anywhere as long as you have unswitched 12 VDC nearby. The wires to those holding tank/battery displays are pretty tiny gauge and perhaps could result in lower voltage than you actually have at the converter panel.
