You are using the battery from your SUV. When you park, disconnect the Airstream. Some SUV have this automatic disconnect. Yours must not. Many have used all their SUV
battery power overnight with lots of usage. The next morning they are stuck with a dead battery.

Does the TV have a relay disconnecting the power? Check the manual.

I would check what else may be running in the trailer. The frig on gas should not pull the trailer and TV batteries down in a week.

When batteries are connected in groups, 2 or more, they have to be of the same size and condition. If not one battery will try and charge the other to it's voltage. I suspect your trailer and TV batteries are not. Another thing to check is the condition of the batteries, TV and trailer, with a hygrometer. Imbalance is not good. You can run on the road with this condition because the alternator will stay ahead of the problem but when parked things don't last long.

I would run an experiment at home of running the frig on the trailer batteries and see if they will last for a week. If you just do this on the road you run the risk of the frig shutting off while you are gone.
