Replacing four CG 6 volts with two Group 27?

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

Whatever you decide, I'd go with AGM's.
Our coach came with four 12 AGM's that someone changed to 6v wet cells. I changed it back again, like the OEM.
Hate fooling around with watering and checking and especially when there's not a lot of room for doing so.
Not only that, our rig has the inverter/charger in the same compartment, with a rubber seal and some vents behind the batteries.
Don't like that either and even if fumes, might not be a problem.
Already had a chassis battery go bad and overheating enough for producing fumes and for setting off the propane detector inside the coach.
Had two boiling house batteries in a previous coach, so again, not very fond of wet cells of any kind and should have probably not replaced my chassis batteries with the standards and even though, they're maintenance free. If for no other reason, I'm beginning to wonder how the charger likes charging unlike cells in parallel, when the big boy relay is closed.
