Engine battery good condition but drained

Can I request for your guidance? We are out camping. RV wont start with the engine battery and starts only with emergency battery switch(using house battery). Is this because the engine battery got drained for some reason? What could be reason? So far no issues with engine battery and this is our 6th camping trip this season. Everything is great. Should if just need to jump start the engine battery? And it should hold the charge after that?

    A good engine battery should go weeks and still crank the engine but a drained/dead battery is a damaged battery. Find the problem, fix it and replace the starter battery.

    What chassis/engine?

    FWIW, our 96 Southwind will not start if it has a little corrosion on the battery terminals. It takes very little corrosion to cause problems.
