Batteries
I'm about to change out the chassis batteries in our Allegro. It has Interstate 31-MHD batteries now. They are original to our 2012 model so I'm thinking they were installed in 2011 making them 5 year...

Interstate 31-MHD are wet cell "sealed" no battery caps. The guy who told you AGM most likely has it as a hot term and knows nothing of what is really installed. Sounds to me like they are the original reasonable batteries for the coach. At five years old they meet my thoughts on age to replace. I use the five year rule on start batteries " if they hic-up after five years service in any rig I replace"
