I havn't had mice since eliminating the entry I created by running a couple wires
from the main battery box over to the aux. box, by using the vent tube to run the
wires. Since I have a non-stock battery I can't use the steel lid for the main box,
and "they" were just following their noses into the cabin by coming up the tube
on the wires I had run. I taped that tube and wire rout shut. No mice since.

I also never leave/store food in the van. I put everything into 2 plastic food
containers and they have sealed tops on them, so the van cabinets have
no food odor from it being stored there.
