WIRING A DC OUTLET

I have a 3124KB.  I want to add a DC outlet next to the kitchen stove, wired to a vacant 15A circuit on the converter.  Does anyone know how to get the wire from the converter, to the rear storage compartment, then to the compartment under the bed. From here the job would be easy.  I am concerned about damaging something in one of the intervening walls.  I believe that the wall between the outside storage and under the bed has metal in it.

Well, dunno if this is an answer or not, but I'd run the wires under the TM through the floor and back up through it again using lots of silicone in the holes after the wires were wired through the two holes. That would be the most non-invasive way of doing it I would expect. That's how I planned to add one for my tv stand across from the couch in my 3023. Hope this helps!  8)
