12 volt battery question
My 2013 Chateau came with a Harris Battery brand 12 volt deep cycle battery. It's a group 27 battery with 160AH with a date of 02/13. I contacted a local place about adding a second battery (group 27)...

As others have said, there is no way a group 27 lead acid battery will have a 160AH @ 20 hr rate. That number is more like the reserve capacity. What you have will be somewhere around 105 AH.
That being said, a group 27 deep cycle (or marine/deep cycle which is more likely what it is) of any manufacturer should pair OK with yours as yours is relatively young, IF and it is a BIG IF, your battery has been well maintained, never discharged below 12.2V, never left discharged, never run low on electrolyte and when fully charged has a Specific Gravity of at least 1.265.
