Second Coach Battery April 20, 2020, 10:16:24 pm I just purchased a 2019 Entegra 31V. Alhough there is room for 2 coach batteries there is only one Harris Deep Cycle RC 150 installed. I tried locally to get one like it, but with no luck. Does a second battery have to somehow "match" the other?Also I realize the onboard geneator provides AC when no hookup is available, but I am not wild about lestening to it run. Anyone recommend a suitable inverter?
