If the breakaway cable is pulled out of the switch, the battery sends power to the brakes, in case of a "separation" from the tow vehicle.

jesilvas - could I use a regular 9V battery smoke detector? I believe all new ones are also carbon monoxide detectors - or is there something else an LP detector will detect that is different?

You have a 9V batt. smoke detector. And probably a separate CO detector. But the LP detector detects LP. Liquid propane. It is heavier than air, so use the one they have. But if it's an 08, I'd say go ahead and replace it.

Step 1. Charge the battery.

Step 2. Connect a multi-meter and check the amperage drawn from the battery. Disconnect the cable and clamp red cable of the multimeter to the battery post, then clamp the black end to your battery cable. You should see less than 50mA, if it's greater than that, then you have some stuff turn on, figure out what it is, you can use the breaker to help narrow down which circuit it may be. Also, a power inverter even with nothing plugged into it, but turned on will drain up to 1A depending on how big the inverter is.

We added a power on/off switch to the battery. Most campers come with it but ours didn't. The display on the radio and the co2 detector ran our battery down. Now we just switch all power off when not in use

Costs $100 to add switch- labor and parts

If it doesn't hold a charge for more than 2-3 days when disconnected, it's dead. Even new batteries can be bad, especially if they have ever been dropped or impacted.
I had a bad new car battery from an autoparts store a couple years ago. When I returned it, one of the guys was restocking and I watched him dropping new batteries onto the floor from about 6". Knew right away why my battery was "bad".

Parasitic drain can be amazing. My new TT doesn't have a battery cut-off switch (I will get around to installing one), and I discovered I was losing over 20 amp hours a day. The factory was helpful in supplying tech info, but net result is, big daily drain just sitting there. Everything that has a circuit board draws SOME power, even when not "in use". The problem is under control - I have 2 6v batteries which provide a theoretical 220 amp hours capacity, and a 130 watt solar panel on the roof. During our (coastal BC) winter the panel has kept the batteries at between 80 to 100% full, but am under no illusions that I'll be needed a generator for extended dry camping. And may go to more solar panels. HTH

Battery cut-off switch. Solves many a problems like this. I mounted ours in the battery case. It has a removable key of which I have 2 spares just in case. Can always put the cable back on the battery by passing the switch. No dead battery problems since.
