That's essentially dead.
Exactly.
Deep Cycle's don't like to be drawn below 50%. Doing so damages and shortens them, reducing the number of recharge/discharge they cycles they have left in their useful life.
Deep Cycle Overview 12v reading is near the 50% mark. 10v is below the 100% discharge rate. The longer a battery stays discharged, the more damage is done to it so get it fully charged asap and then get it load tested. Chances are you will notice a significant decrease in performance (doesn't last as long before falling below 12v now as it did before) if it takes a charge at all.
Sounds like time for a new battery most likely. Good advice on getting a couple and solar if you are going to be doing boondocking. Would also suggest a battery monitor that gives you a voltage reading and not relying on the typical 4 light tank/battery monitor that most RV's come with.
Here is one that many use that are concerned with keeping their batteries in great condition, monitoring closely because they boondock a lot.
