Marine/RV Battery

"MOST battery problems are NOT caused by the battery, but by the consumer that abuses the batteries." Doug. I learned this the hard way. When I first retired and bought the MH, I bought 2 Trojan 6v GC batteries for the house and a Trogan 12v Marine battery for the chassis thinking they were the best based on what I heard on this forum. They lasted 4 years, and people said that is normal because I dry camp 95% of the time. I replaced the house batteries with 2 6V Sams Club batteries and the chassis with a starting battery from Walmart. Spent 1/2 of what I would have paid for another set of Trojans. The starting battery lasted 9 years and the Sams Club batteries are still in use after 12 years. The difference was I learned how to maintain the batteries better using just a B&D 40 amp charger and just charged the starting battery at the same time I charged the house batteries. Maintenance is more important brand.
