I had forgot to turn Radar Detector off,,,

You can get all the OPINIONS you want on the internet, but if you really want to solve your problem you need FACTS. Buy a basic multimeter for under $20 and find out what is really going on. This is a decent one:
Robot Check

Once you know how many amps are going out of the battery, you can go in the right direction for troubleshooting.

You'll need to add an amp clamp to that unit to find amps.

This one is serviceable for all RV needs and the clamp makes it easy to see amps being drawn on any wire.

The factory installed main battery disconnect does not shut off power to all things. This is true on FR products as well as several SOB's. The CO2 detector, level-up, and another parasitic item or two stay directly connected to the battery. Several of us have installed our own battery disconnect directly to either + or - cables (depending on your personal philosophy) right off the battery(s) and solved the issue of a battery going flat in a week or less while in storage.

I sort of have the same issue but the suggestion for a battery shut off will not work. We have a battery shut off installed but we cannot use it in this instance.

We are camping 3 wkends at the same campground but we must be unplugged to be permitted to stay on the site during the week. With my previous camper, also a FR product, we turned the refrigerator to gas, left on a Sunday, came back on Friday and everything was fine. I tried that last wk and came back to spoiled food and warm a refrigerator. I walked thru the camper twice to make sure nothing was left on. What could be happening? I read the thread about the fridge heater switch, but we do not have such a switch on the fridge.
Any help greatly appreciated.

Does it get cool on GAS when you are plugged in and things are turned on in the coach? Or does it not work on gas no matter what your plug in situation is? If it doesn't work on gas no matter what...then the first place to check would be that the propane detector is operating correctly and has a green light...that is an automatic circuit that cuts off the gas tank solenoid switch if it is not working properly.
If you do have it working on gas when plugged in ...but it fails when the batteries are disconnected...it could be a refrigerator 12v circuit....check your manual or provide the make/model here so someone can check if such a circuit exists.
Alternatively, it could be that the propane detector is wired into the cutoff switch rather than direct to the battery terminal...moving the wire so the switch doesn't affect it would solve the problem.

The other possibility is that your fridge DOES work on both power & no power (battery) ....but that your battery is failing and has lost most capacity so it starts off the week fine...but the drain of the propane detector eventually drains the battery and cuts off the gas solenoid leaving your food warm and spoiled by the time you return. Solution is a new battery with enough capacity to stand up to DOUBLE your parasitic drains on it while you are away. To figure out those drains you need an amp meter (DC clamp meter) after you've be plugged in for at least a day or two. Unplug...turn off everything with the kill switch...and clamp the red battery wire and you'll be reading the parasitic amp drain while you are away from the coach. To keep things simple...lets assume you find a 1/2 amp current still running.

This means your batteries are losing 1/2 amp per HOUR...1 amp hour every 2 hours and therefore 12 amphours per DAY. If you go away for a week...that is 7x12 or 64 amp hours...3 weeks 250 amp hours or so.
So you must have a battery bank of TWICE that or 500 amp hours to support your use while away from the trailer for 3 weeks.

Now it is much more likely that you will have a much smaller amp drain and need much less battery power...but the math work is the same.
If you show a 1/10 amp draw then you use 1 amp every 10 hours...and 2.4 amp hours each day etc. etc. ....just make sure the rated deep cycle amp hours of your NEW coach battery is at least double amps you use on your absences in storage time.

Good luck!

Thanks for all the suggestions.

Yes, the fridge does work on gas with electricity and without.
This past wkend there was an issue with the electric at the campground and we were with out power for 6 hrs. Fridge worked fine. Last wk the fridge must have stayed on at least for a few days, because some of the items in the freezer were still cold.

I will tell my hubby to bring along an amp meter and see if we can find a drain on the battery. The battery should be fine as it was new, July 2015 and it was stored properly off the camper inside during the winter.

Could carbon monoxide detector be the problem? In our old camper the radio stayed on and we just pulled the fuse on that before we left. All I left in the fridge this past wkend was soda. So we shall see if we have cold or warm soda on Friday.(so nothing will spoil) I must make a point to check the battery power first thing, if the fridge is not on.

New camper - new problem.
