Well Sir,
First off, may I ask, what the reason for the replacement alternator? Did it give up the ghost and stopped charging? Did it seize up? What? And, did you replace the chassis batteries just because you replaced the alternator? Or, were they not up to par in starting the coach or what? Just trying to build some history here.
Now, first off, if you have a Volt-ohm meter, and, no how to use it, what exactly do your chassis batteries say, when the engine is OFF? Now, that do they say when the engine is ON? And, take the readings at the battery posts, not any other place.
Second, just for your self assurance, have those chassis batteries load tested to make sure, they're good and, will handle the typical loads, associated with RV chassis duties.
Third, if you're still finding that there seems to be a higher than normal (there's always what's called "parasitic" drains on both sets of batteries) drain, then it's time for further investigation. The simple quick test is, disconnect the main ground at the chassis batteries. Put a 12V test light in between the negative post and, the cable end. If it lights up bright, yep, you got a "short" or, something's left on like interior compartment lights, interior coach lights inside the coach someplace, or, some other 12V appliance of some type.
A bit more tedious test is to, leave that test light in place, and, start pulling the 12V fuses for 12V operation (water pump, furnace, lights, and any other potential drains) in the coach, one by one, and see if that light goes out, after pulling any particular one. If it in fact goes out, after one is pulled, then you have at least an area to start looking, to find out why that circuit is causing you problems. Good luck.
