Just purchased a 2016 Sunseeker 2400WS with 26k miles on her. The gentleman who I bought it from was meticulous with his maintenance, but I did notice this morning that the house batteries look to be original. He did much of his RV'ing fully hooked up. Time to make lemonade from lemons and upgrade to AGM's or Lithiums! Very excited to learn, I'm appreciative to have found this forum! The research begins!
Before you replace the batteries, have them checked out to see if they are still good. No sense replacing good house batteries before their time.
Welcome to the forum!
