6 or 12 volt?

[Denny and Angie Miller]

This question is to anyone who has the electric (not hydraulic) auto leveling system and has switched from 12 volt to 6 volt batteries:
Are you happy with your switch to 6 volt?
Do your leveling motors operate better?
Did you get (2) or (4) 6 volt batteries?

The details:
Its time to replace my batteries. I bought the trailer new, with interstate deep cycle 12v batteries (2) and the leveling motors have always sounded as if they are overloaded when lifting the trailer. Lately the breaker often trips before the trailer is level...in the past that would only happen when I tried to lift the tires off the ground using the leveling system (I only did this a few times). I suspect the batteries are weak and as the voltage droops during operation the motors pull more amps causing the breaker to trip (as designed).
The trailer is always plugged in to 50A shore power, we have residential fridge, no solar or plan to add it, and never boondock (no desire to either).
The battery charger is the 3 stage type from WFCO (WF-9865).

I'm also going to look at *possibly* replacing the circuit breaker with an additional 10A beyond what is currently installed, but no more than that. (I don't know what is installed yet)...NO I'm not going to install the 80A...that "fix" is for some hydraulic systems.
Battery maintenance is not an issue so I can get wet or agm batteries, but I'm not dropping the $ for lithium. If I had solar and wanted to boondock, maybe. Yes I've seen the videos on lithium cost over lifetime.

I would appreciate any replies from those who have my similar set up and have switched to 6 volt
