TV Shut off when key on bypass

In 36 years as a professional RV Tech, I have never heard of, or had a customer get a ticket for having a TV ON while in transit. There is NO Federal law that governs this. There are some states that have a law that states that IF the TV is visible from the drivers chair it must not be ON. NOT that it must be disabled, just that it cannot be visible for the driver while in Transit. There are some motorhomes that the front overhead TV is not visible to the driver. That said, about 50% of Motorhomes have a OEM Ignition disable system. I have NEVER seen a DVD/VCR connected to the Ignition disable system, ONLY the TV. I guess there are some that disable both 120 plugs instead of just the TV. MOST Ignition disable system are extremely EASY to disable or bypass. Both Fleetwood and Monaco had HOT 120 plugs right next to the Ignition disabled plug, so you just unplugged from the Ignition plug and plugged into the hot plug next to it. As a practical for the OP, it would be best and very cheap to just install a extra DVD player in the rear bedroom. DVD players are cheap. Doug
