I’m assuming the Xantrex charges both start and house batteries?
What happens to the start batteries if the charger is set to AGM?

My four six volt batteries need replacing Again. Five years again and shot. I have a watering system but I leave the rv plugged in all the time and I forget to water them and they dry out.
Im pretty sure Im going to replace them with two Group 27 12vdc dual purpose maintenance free batteries. I chose those as the have the same footprint as the CGs and fit the rack.
I just replaced my 8 year old Group 31 starting batteries.
They were starting her just fine but I felt they were too old
We never boondock, we dry camp maybe once a year. I have replaced all the light bulbs with LEDs and the tv is LED too.
It has a 2000 watt inverter which might get used with tv. The microwave would get unplugged if boondocking.
Crazy? Stupid? Saves about $300 and some maintenance. Easier to change out, too

More internet fuzzy math... {Keep in mind that there are 3 kinds of people on this planet, those that can do math and those that can't.} :B Two group 27's that offer a total of 200 amps give you 100 useable amps, not 40 - 50.
Most folks overestimate how much DC they actually use {Spending lots of time and money searching for a solution for which there is no known problem... the government does this a lot}.
:S
Our two, 4 year old, Interstate Group 27 {true} deep cycle batteries give us an easy 3 - 4 days of normal use off of the grid. Since we rarely stay in one place for more than 3 or 4 days and driving just a few hours tops them up nicely we rarely run the generator. Our coach is 7 years old and the genny has 85 hours on it and yes we are off the grid most {60 - 70 percent} of the time.
We don't have slides or electric steps, don't watch TV or movies, just a couple of hours of lights at night - I read and my bride journals {absolutely no reason to spend the $$ for LED's}. The water pump draws so little as to not even be a consideration.
The one big draw is the furnace {the squirrel cage fan} but with a 35K BTU furnace it runs so little as to not be much of a factor and then only for a few months of the year {yes we RV year round out here in southern Arizona}.
My batteries require regular topping up and that frankly is a PITA. I may spring for AGM's when these finally start to go but at more than twice the price I will probably suck it up and keep watering them.
One thing I learned in 35+ years of boating is that the two biggest lies in the English language are:
Waterproof and maintenance free.
As always... Opinions and YMMV

Maintenance free means you can't add water. If your converter is cooking batteries and you can't add water your problem will be worse. I'd get a better converter first. After that. If you never dry camp any ole battery will do.
