Battery Light stays on
I crossed the jumper cables when jumping off the mh (bad brain lapse). I corrected them correctly and it started and ran fine. I then started the generator with the engine running and it stopped the...

Your generator likely has a circuit that charges BOTH the house and coach batteries, interconnected with an automatic 'switch' between the batteries. Many add an isolator between the batteries so using the coach doesn't leave you stranded with a dead starting battery.
It's possible you killed BOTH batteries in your accidental (high amperage!) short. Your generator *may* be drawing power from the coach battery or both to start, masking the other dead battery/shorted cells.
Did you have both batteries tested?
You can stop at Advanced Auto Parts and they will test your batteries for you, free of charge.
As mentioned, check the voltage across EACH battery at rest and while the engine is running (charging) for testing the charging to each battery.
If I were to guess? You toasted the house battery and when charging it is pulling way too much amperage from the alternator as it tries to charge both coach and house batteries. But I wouldn't bet my entire stake on it ;)
