I don't normally leave my camper hooked up to the TV for a long time other than when I driving. Yesterday I had it attached for a few hours before leaving the CG and Uhhhhh... the battery was dead. I stopped for dinner and when I arrrived at the restaurant, turned off and restarted the TV fine. Came out from the dinner and it wouldn't start again. Got a jump start again and drove home (4hrs) with everything running fine. It was late so I left the camper hooked up (not thinking there way a problem) and for the third time... dead battery. >:(
Now, here's the weird part. I unhooked the camper, drove 15 min to work and it started up 3 times including over lunch without a problem. Any thoughts? With the galley down, I thought most of the power items were disabled. (furnace, radio, lights, water pump, etc) I thought the only things working would be brakes, outside lights and carbin dioxide detector.
You could just unplug the wire harness when you park for extended periods of time. You just have to remember to plug in again before you leave O0
The fridge being on 12v does sound like it is the cause.
****QUESTION***** Why does the fridge have a 12v option if it can suck a battery dead so quickly?

The path of least resistance is directly to your TV battery, It won't get to your Deep Cycle battery until it gets no more from the TV battery.
Remember your TV battery is high power for a short amount of time, the deep cycle battery is level medium power for an extended amount of time.

My vehicle did not come with a charge line so I added one directly to the battery, always hot.
I found the sun roof fuse (an option I don't have) was only hot with the ignition on so I used that as a power source to a relay.
Now the charge line is off with the ignition.

So it can be run on 12v while the vehicle alternator is spinning.
good question rabird, someone else will have a answer that question.
I had the fridge on 12v because after doing some testing, the A/C takes 24hr to cool down to temp which doesn't work when I'm only at most CGs for the weekend. I also didn't have a light on me for propane when pluggin in the utilities so I went with 12v. - Learned the hard way :banghead:
Joe,
Don't even think of running the Avalon's 4.2 cu ft fridge on 12v. You'll have a dead battery in minutes.
When hooked up to the TV, it couldn't keep up with the draw. Pup's battery would be dead by the time we arrived at cg even with the charge line.
Fortunately it ran well over the road on propane.
