When To Replace Coach Batteries?

Both times I've changed out my house batteries have been while camping. I've found that when they fail they just go out. Basically working fine one day, gone the next day. First time I pulled into a camping world and changed all four batteries out in the parking lot. Next time I got smart and drove the toad to Costco and got cheaper and better batteries and brought them back to the campsite and changed them. Didn't really need to do it on the road that second time as we had shore power but it really wasn't that difficult to change them.

. Were thes 12 or 6 v batteries? My 6 v ones seemed to just lose capacity but my 12 v ones seemed to go all of a sudden.

Actually I should have been more clear. They were 6 volt, and when they went bad it was my fault for not keeping up on the water level. On the first set when I saw the low water and it took almost a full gallon to fill one battery back up, I knew I screwed up and the batteries were shot. I filled them all with over 3 gallons and they did not hold a charge. Thought I learned my lesson but did the same thing a second time. Then I bought the battery fill kit where you fill them all at the same time with a little hand pump. So now I keep distilled water right by the motorhome in the storage shed and before every trip it only takes a couple of minutes to plug the hand pump in and make sure the batteries are full. I also used to leave the motorhome plugged in all the time while it was in storage by my house, and that seemed to really drain the liquid out of the batteries. So now in storage I disconnect the house batteries with the switch and I put a separate trickle charger on my chassis batteries and everything works great.
