I'd like to route some cables to the roof of my westy (luggage rack area) and was wondering if anyone has
come up with a good, inobtrusive way of doing this.

In general, if you have to punch a hole through the roof to run a wire, what is the best way to do this that
ensures that the wire won't rub through the insulation and that no water will come in?

Thanks,
...Markus
