It seems as if I can't get the batteries (both engine& house) won't last but just little over a year..I try to maintain them,water,running the engine , etc, but now I need 3...in looking at the dates ...
Do you let them run down between trips? Or are you plugged in? Have you ever checked the battery voltage? Does the Chassis battery get charged when the House battery is charging at camp?
I think the short life is a maintenance issue more than the brand. Lead acid likes to be tip top 100% charged. If parked in the sun 100 watts of solar would go a long way for battery longevity.
