If the coach runs with the jumpers on and trys to die when they are removed the answer is obvious. You are not supplying the coach with at least 10 volts to run on. What is causing that? More likely the alternator than the battery since it should run on the alternator after the engine starts. However the battery could be damaged due to the defective alternator. There is a simple test to check to see if there is anything draining the battery when all switches are off. Remove the positive cable and touch it to the positive battery post and see if there is a spark(it might be hard to see in bright light). There should be nothing that draws enough current as to make a spark. If there is one you may be able to locate the draw by removing fuses one at a time. I hope this helps you with your problem. Good luck.
