Coach batteries toasted?
Can't run the cabin heater through the night without draining the batteries down. Seems very strange that it would need so much power. Should only be the electric fan that needs the electric power? ...

My thoughts:
I do not believe they make group 24 'deep cycle' batteries. I'm sure you have marine 'hybrid' batteries.
From your comments I'll suspect you have neglected your batteries. If so, they will never return to maximum, like new capacity no matter what you do. I seriously doubt they can still provide close to 80Ah/charge.
Now that you better understand the importance of proper battery maintenance it may be prudent of you to start over with new batteries and see if you can protect them better. A pair of group 27's would be better than the 24's but you may need more. Do a power audit to determine your real world needs. Do you have room for bigger batteries? I don't. Can you properly maintain and charge a bigger pair?
Not knowing your camping style this could be delayed to a later date. Do you foresee relying on them to supply maximum potential in the near future?
FWIW: I neglected my first battery when I was learning. I never paid any attention to it until it started to fail after about two years of use. Now I equalize them every three months, top off with water when needed and they can last for at least 6 years or longer. The question is do you want to put in the effort to maintain them for longevity or just replace them every few years as needed?
