I installed a battery isolation switch on my TT. When not it use, the battery is completely isolated from the trailer electrical system which completely eliminates any possible parasitic draw.
Second, when not being used, especially in the winter, I keep it on a battery tender which has a desulfating function.
The battery tender had the battery connection pigtail with a quick disconnect that I can plug and unplug the battery tender at will. It takes me less than a minute to isolate the battery and connect the battery tender each time I return from a camping trip or when I winterize my camper. It stays on the battery tender from November until April during our Wisconsin winters. Never have to worry about the battery not being topped off or just plain dead.
The battery isolation switch, if your trailer doesn't have one will cost you $25 for a good one and I would expect to pay $25 to $50 for the battery tender. You can get them cheaper, but it isn't something you want to use to cut costs. Continuously replacing $100 plus batteries is the result if you don't spend the money up front.
