Can I get voltage sensitive power control?
I'm putting a wireless backup camera on my car hauler trailer and I want it to be powered up only when the truck is running. So I'd like to use the hot feed coming from the truck to power the trailer ...

Ok, in that case, take my last post and remove all reference to "HOUSE".
Just charge the brake battery when parked using a battery tender
And use the charge line from your towed to power the camera.. TWO independent systems, one powered by the truck and the emergency brake battery operated.
No need for any fancy electronics, just the already existing isolator in the truck.
You could still charge via the truck- just add a diode in the charge line after the camera feed. As long as the charge line was switched, it would work fine.
