I'm sure there's some point to that photo, but darned if I know what. It's not from a toyhauler?
I had to pull the front of my entertainment center off to do some additions and the wiring back there was just an astounding mess. Three of the wires were so short that I couldn't open the covering more than an inch. Just ridiculous.
I also had to put one of my speakers back in the ceiling. They are pretty heavy little dudes and they were just secured, if you can call it that, in the 1/2" ceiling board by some wood screws, no anchors, nothing to really hold them in place. I need to put expanding anchors in the rest of the speakers next spring.
