WFCO converter & battery questions

I have the same converter on our trailer and have been making it work for us nicely in a dry camping situation. We camp for about 8 days in the Smokies with a single Trojan SCS 200 12V (Gr 27 115AH) deep cycle battery using a Honda EU1000 (also have two EU 2000s but don't take them) that I run for a few hours every morning. When I first connect the generator the charge curent for the single battery is on the order of 12A and when it tapers off to around 3A I shut the generator off. I have been using this technique for over 10 years and always have plenty of battery power. We have the normal trailer loads plus run the Fantastic vent fan all night long when we are there in the summer.
