You also really need to research your on-board CONVERTER/CHARGER. This is probably why your original battery has gone KAPUT in the first place. You need to replace your on-board converter/charger with a SMART MODE unit.
Going with two 6VDC GC2 Batteries from COSTCO/SAMS CLUB wired in series will give you a good 220AHs of battery capacity which is great for the camping off the power grid. These batteries will need a good 45AMP Converter/Charger unit or bigger if you like in case you add more batteries later on.
The SMART MODE converter/charger like the PD4600 or PD9200 series will take great care of your batteries for you. All you need to do is occasionally check your battery fluids.
The other big battery killer is running your batteries down below 12.0VDC (APPX 50% SOC) and not recharging right away. I watch this very closely when camping off the power grid. What I did was plan out all we wanted to use to use in a one day/night camping run off the batteries so that the battery bank would drop down to around the 12.0VDC charge level at 8AM the next morning. Then we re-charge the batteries by connecting the trailer shore power cable directly to our 2KW Honda Generator 120VAC receptacle using a RV30A-15A adapter (WALMART) and use the on-board smart ode converter/charger to recharge our battery bank up to its 90% SOC in a quick three hour generator run time. We like to do this during breakfast so we can also make our fresh coffee supply poured up into a thermos carafe which only takes about five minutes being connected to the 2KW generator.
This is what we do when we camp off the power grid...
