Dual battery in 5th wheel

This is what is balanced and best for twin twelve volt batteries.



As it often doesn't cost a dime more to do this, I think it is worth the trouble.

If you wish to understand the "why" surf here:

correctly interconnecting multiple twelve volt batteries

Others may say it doesn't matter--but unless there is a compelling reason to not optimize charging and discharging why not do it the best possible way?

On practical side, the only difference paralleling batteries of different age/typ makes is storage.
Left alone for long time the weaker battery can take better battery down, so they should be disconnected.
During normal charge/discharge life all the batteries will take or give.

I agree.
It's best if the batteries are the same type and age but they will still play well together even if they're not "matched".

You might get even better info posting in the fifth wheel forum.

Thanks for the quick response.
