Not sure how you have six-year-old batteries in the 2013 motorhome? For your usage I would go back with a single AGM battery and forget about it for six or eight years. Yes, I know you said no AGMs but once you've had them you'll never go back to the regular lead acid batteries.

Thanks, but since you don't intend to influence my judgment and don't advocate that I do what you just said, I'll ignore it. :) (That was a joke)

It's a 2013 model-year, which we bought in 2012, and which was manufactured in 2011, with components at least that old, maybe more. Therefore, the batteries are at least 5, maybe 6 (or more), years old.

Thanks for the suggestion, though.

Typically, at least for trailers but I suspect also for motorhomes, the batteries are installed by the dealer. Certainly I would not expect the house batteries to be the same age as the chassis, nor for a manufacturer to keep them sitting around for months before installation.

To be a 2013 model year, it could not have completed manufacture any earlier than sometime in 2012 per federal law. A vehicle maker may change their model years at any point in the year, but the numbering comes from the vehicle year that spans January 1st. (In other words, if they change over in March, then the vehicles made from March through December get the next year's model year, while those made in January and February get the current year's model year.)

As others have suggested, if you are getting two batteries, it's usually the most cost effective to get a pair of 6V golf cart batteries (provided you have sufficient height in your battery compartment).
