VIc, On your new panther, if it is still in the build stage by ATC, have Jeff & Marty NOT use staples on the interior wall panels at the bottom. I asked them to use the same screws they used on the sides and top of those interior wall panels. That allowed me to undo and completely remove the interior wall panels, so I could do my 12 VDC wiring, inside the walls with the same technique used by ATC; a drilled hole through the aluminium frame with a piece of plastic tubing through the drilled hole, then the wire through the plastic tubing. When you're all done, simply replace all the walls with the same screws. Makes for a very clean installation.
