And therein lies the rub ... that G31 AGM you've purchased is rated at 100 AH so at a 50% depth of discharge you've only got 50 AH to work with, enough to get through a day or maybe two at most, obviously depending on how often you may use heavy draw items such as your furnace which is capable of drawing down a single battery in no time at all. :E Sure, an AGM battery will tolerate a deeper depth of discharge on a repeated basis than will a lead acid battery but with just one battery you'll still be quite limited. That's why most who have more than an incidental interest in dry camping will carry at least two batteries while some carry four or even six. That then raises the issue as to how you're going to recharge them, the answer usually being either a generator or solar, neither of which is an inexpensive solution either. Fact is, anytime you cut the cord you have to really carefully consider just what it is you expect to be able to run on battery, for how long, and how your going to maintain those batteries. I suspect most who understand these issues would most often recommend a pair of 6 volt GC-2 deep cycle batteries such as the
Trojan T-105 which is rated at 225 AH, meaning a usable 115 AH at 50% DOD, along with either a generator and/or 300 watts of solar to effectively maintain those batteries. However, that in turn then raises the question as to whether the converter you have in your trailer is capable of meeting the battery manufacturer's charging requirements and if not whether you're willing to replace it with one that does. Unfortunately, the reality is that if you want to dry camp any more than just incidentally it takes a lot more than just throwing a lot of $$$ at a single AGM battery and calling it good.
