Deep Cycle Batteries
How long do deep cycle batteries usually last? How often should they be replaced? Thanks.

They last until they no longer hold enough charge to do the job you want them to do. I've seen them last 10 years or more, sized well to the job, properly maintained, no excessive discharge, no charging mistakes.
I've been getting 3-4 years in RV use, a pair of batteries that don't work very hard, but spend a lot of storage time self-discharging, and are charged only by a two stage on-board converter-charger. I could probably do better if I could do maintenance charging in storage.
I have friends who have difficulty getting two years use, because after their batteries discharge in storage, they are worked too hard when already at a low charge state, in the process of getting the RV out of storage.
