12V Delayed Shut Off?
Do the 12 volt power outlets have a delayed shut off or do they stay hot? I thought they stayed on, but I've noticed a few times that something I forgot to unplug had somehow turned itself off. The manual seems to indicate that they stay on.
If there is a delayed shut off, how long does it take to shut off? Is there a choice of settings?
Thanks,

The 12 volt outlets remain live for 30 minutes if the ignition is in ACC mode and 75 minutes if you shut the vehicle off.
The 110 volt outlets are live only if the engine is running and can supply 400 watts (about 3.6 amps) in Park and 300 watts (about 2.7 amps) in Drive.

The DC draw is mostly irrelevant since the inverter only operates with the engine running. You need to know the current draw of the device that you're plugging into the 110 volt side. Exceed the limit and the inverter goes into a shutdown mode.

I don't think it's irrelevant. 30 amps is a whole lotta current. If the wire's aren't big enough, you can end up with real problems at that current.

Factory time out on the 12V outlets is 1:15. This can be changed using Forscan to on all the time to any amount of time from a few seconds to hours.
Problem is that the battery monitor will turn them off if it thinks the battery is getting low. On some trucks this is very quick..
I came up with a mod to the engine fuse box using a jumper wire to provide power straight from the battery to the outlets.. This bypasses all protection so you can kill the battery if not careful..

I think it depends if you have something like a cellphone plugged in. In that case, it seems to be more than two hours. If I had nothing plugged in while it was turned off then plugged something in, it won't charge.
