Thanks for the suggestions and details from the three of you. If I read you all correctly, you are usually plugged in to shore power. Are you aware whether your batteries ever get drawn from any significant amount? Is is possible that since they don't ever get down even 40-50% and always have either alternator input or shore input at carefully managed levels right after any brief discharge, they last as long as they do? Do you know if the life you are getting is possible with wet cell batteries that are used more rigorously provided they are fully recharged daily?

My original equipment batteries (both coach and chassis sets) failed in 2 years due to a "perfect storm" of dealer neglect and our inexperience. I'm trying to learn how not to repeat the errors when we choose our replacement set, whether they are wet, AGM, etc. We find the possibilities of battery maintenance errors even more intimidating due to the 40% greater cost of them north of the 49th parallel.

Thanks for any additional input you can offer.

I can see your concern. Mine failed in the first year for much the same reason. The PO let them go dead and they froze.
Your best bet for your batteries is to keep your coach plugged in when your not using it. Even if all you can get is a 15 or 20 Amp service which is sufficient to operate the converter and keep the batteries fully charged. (All other appliances turned off of course).
If power is not an option, your next best is to install a battery cut off switch on the negative terminal of both the house and chassis batteries. (NAPA or similar store can supply these). Make sure they are fully charged before you park, turn the switches off to isolate the batteries from any parasitic load, and they should be good for at least a month. Once a month or so (you will get a feel for this time frame as you get used to it) go to the coach, turn on the switches and start the generator. Run the generator with an electric heater or similar appliance for at least a couple hours while you have a game of crib, few beers etc. Check the battery voltage, should be 13.5 VDC. Shut down and turn off the isolator switches until next time.
Just don't let them run down to 50% or 60%. This will destroy your batteries.
Hope this helps.

Part of careful 12V energy management includes making sure that the SOC, (state of charge), of the batteries never drops below 50%.

Batteries should always, and only, be recharged based on the SOC, (which can't measured in days).
