Chassis Battery Opinions October 25, 2019, 10:53:57 am I'm starting to research replacing the Chassis Batteries on our 2007 Intrigue 530 CAT C-13. We've owned the coach since 2016 and haven't every had a starting problem. However, I can tell they are starting to age (they struggle through the first turn of the starting motor). I'm thinking Interstate or Lifeline. I know both are spendy, but I'm resigned to paying for quality and save the headaches down the road. I'm guessing battery opinions are like tire opinions, everyone's got one. Bring 'em on!
