Batteries have a few failure modes
Shorted cell
Open cell
High resistance (sulfation causes this)
Boil dry
Now if you have one battery (Two six volt in series = one big 12 volt) unless you have a really really big charger/converter failed is failed for the most part.
But if you have series/parallel (example)
-6V+-^6+=12 volt
-6V+-^6+=12 volt
Or 12 volts in parallel
If one fails Shorted. especially if it's 2 cells. the other can push enough current that BOOM (or to be more precise POP)
Home was where I park it. but alas the.

after a semi "nicked" it. Still have the radios

Lead acid batteries, including AGM, can explode if that are short circuited or run very low on water.
Rare, but it does happen.

Hi,
What converter do you have?

On my pickup camper I have two 12 volt batteries in parallel. The camper was not plugged in so the converter/charger was not powered. I do keep a maintainer connected to the batteries. One of the batteries exploded. The other one was okay. Fluid level in the one that survived was low but still covered the plates.

Everyone, please note the OP is driving a DIESEL PUSHER!! It would be safe to assume he has a three stage charger/inverter which would seem to preclude a high voltage "converter"
Looking more like a defective battery and the manufacturer is running away from it.
Today is my personal best for most consecutive days alive.

I dont think thats safe to asume at all, My parents bought a 200K dp and it had a crappy two stage in it, my buddy just bought one and he has to change it out, so I have seen more with two stage than I have with three stange, not that I have seen a lot but the ones I have seen were all bigger brands.

I have seen far to many battery explosions. One right under my sit down. Yep, on a golf cart.
I am an electronic tech and diagnoses battery issues thousands of times. Always wear some sort of eye protection around a battery. One spark or even one that goes bezerk internally. Usually an old one or one that has been overcharged. A battery temperature sensor can turn a charger into a boiler.
Folks are mentioning low water levels and that can be a clue. For now if those batteries have any age on them it would be a good thing to get rid of them. You need to pull out all the batteries (after lots of pictures of course), and clean everything with warm water and lots of baking soda to get rid of the acid that will eat everything in sight and beyond.

I have pulled the batteries and flushed everything in the compartment as best I could. I also covered everything with a baking soda paste and flushed it a second time. I will paint it all today if its dry enough. This is a Monaco and has a 3 stage inverter/charger. It is always powered up if that matters. Someone mentioned golf carts and my friend had a battery in his explode in the garage. The top of the battery went through the roof of the cart and the sheet rock ceiling of the garage.....I'll let you all know as I progress here as I had planned a trip for next week

I got paid by a lot of people to do boat work for a lot of years.
One of the reasons I advise against paralleled jars is the common occurrence of battery explosions. I have seen (and cleaned up after) battery explosions from all possible arrangements and yes even single jars. The fact is, paralleled jars make it more common. At least, I got paid much more often to clean up and make repairs after explosions of paralleled banks.
About all you can do if your load requires that big a bank is to separate the sections by gunga moma fuses that will let go when one cell in one jar goes short and then the rest of the bank can't gang up on him.
I used to keep disposable rain gear and gloves and such in the coach along with several boxes of baking soda for just such events. Insurance companies made my time worthwhile.
