Battery replacement..have SRM27 Interstate
I follow two different approaches to the batteries that I utilize in my coaches. For the Overlander, I utilize a very high quality AGM RV/Marine Deep Cycle battery because it has an advanced charging system (solar with inverter/charger installed by AJL Solar) - - these batteries were very costly, but are now in their fourth season showing no evidence of age. For the Minuet with its Magnatec converter (installed two years ago), I utilize a Die Hard RV/Marine Deep Cycle battery or its equivalent as the Magnatec has demonstrated its propensity to boil the battery (by shopping for an early season sale, I can often obtain one of these low-end batteries for around $60). I am happy to get one full season from the battery under those conditions and ecstatic when the battery makes it two seasons as the current battery just completed its second season.
Good luck with your battery quandry!
