I did this for a solar panel rig.  I drilled through the
rear inside wall of the luggage rack.  There I installed a
waterproof marine connector (like the military ones
with screw-on weather cap). I then a hole
in the roof of the van between the rack and the canvas (so
it's covered and weather-protected with the pop top down.)

Thence underneath the headliner (had to take out screws and
pull it down a bit) and down through the door pillar.  You
can access that space from the bottom through the ventilation
hole.  I the drilled through the pillar wall back into the
van inside (I put my charge controller on the composite wall
that faces the rear of the driver's seat).

I remember it took a while, and it is no fun drilling holes
through that thick German sheet metal with a hand drill.

Will publish a few pictures if anybody wants.
