If your battery is indeed down to 2.8V in the morning I suspect the repeated discharges have basically killed the battery. Anything below 10V is down to almost 0% charge.
12V batteries are usually a combo starting/deep discharge battery and can't take many discharges down to below about 11V before being damaged. Even a high quality 6V deep discharge won't take more many discharges down to 10V. They will take 100's down to about 11V, dozens down to 10V. Few down to 2.8V.
At this point, I'd have the battery load tested and most likely replaced. then you can repeat the tests. the tv amp is load you don't normally want on. likewise with the fridge, it shouldn't draw ANY current with the fridge off.
you should easily be able to dry camp for several days with two 12V batteries as long as your carefull with the lights.
