6. Am I crazy thinking about replacing this battery? Is there something else I can do to prevent it from draining so fast?
I don't think you are fully understanding the problem.
If you leave the headlights on in your car overnight it will kill the battery.
You can replace the battery but if you leave the headlights on overnight again it will kill the battery again! THe problem is not the battery but the headlights!
The headlights or some rv gadget are being left on in your RV and killing your battery. The battery cut off switch is not cutting off everything. You need to figure out how to get everything turned off. The problem is not the battery
