How long can I go without electricity (plugging in)?

I have done some inverter systems so I have calculated loads and estimated run times. So here goes. 1)76 amp hours is really 35. Why? Because you do not want to draw down your batteries past 50% on a regular basis.2)add up you loads. They are listed for each item. The best way is to turn on all the gadgets you normally run and use an amp meter to measure the total draw. Google the formulas. But for example if your fridge draws 5 DC amp hours then it would last 7 hours. This is a simple example and if you read into the math your head will pop.
but it’s a good start.

I'm curious as to how much draw you discovered.  While I have a T@G, the entertainment system is the same.  I've never had any issues with the drawdown but always like to gather data for future use.  In addition, I've not considered turning off the juice to the radio because I'd lose my presets and time.  Not a big thing but more fiddling.  I have also never found the light on the radio to be an issue either.  For the TV, which seems to be brighter for some reason, I just put a piece of vinyl tape over the light.  Knocks it down by 50% or more.

I also noticed that you must have pulled the door stays off?  Any thoughts on that?

@RollingBnB, that feature was not available with the 2015 Jensen.  The only way to totally dim on mine is to have a separate on/off switch. Me, I just leave the bathroom door open when sleeping so the organizer on the door shields me from the light.

@bikegirl...I say 2-3 days.  Do you have one of those cigarette plug volt meters?

I have a 2016 which does have the feature to completely turn off the blue lights. Even with them dimmed, the unit draws juice. I'm guessing any device that uses a remote control is always "on" even if no lights are activated. Can't recall the exact amp draw, but it was enough for me to eliminate it. installing a 12v switch can be accomplished by someone with basic electrical skills. Be careful with size of the switch - there is very little room in the Jensen cabinet.

@ScottG Thanks.  I do not have the  dimmer option.  My primary reason for wanting the on/off switch is for parasitic draw purposes.  I do have a piece of cardboard over the panel now to block the light.  Guess I'm going to have to get an electrical book and start reading.
