Switch to LIFePO4?
I have a trio of Rolls Surrette FS210 wet cell batteries that give me about 315 AH of usable capacity. My big concern is weight, the total is 400 lbs in my from compartment of the 5er, and I think tha...

From my experience charging using my eu2000i generator I'll set the incoming power on the Magnum 3012 to 15a and it will charge at 100a (.2c). I only run the generator for 2 hours just to give it hold over of 200ah (40%) boost and let solar do what it can. This is only when the batteries don't get to 60% SoC by 4-5pm with decent weather in the future. That gives plenty of power for the night usage and still make 12 cups of coffee and use the microwave for breakfast. When done be at 25-30% SoC.
If plugged in which hasn't been in 933 days as of today, I'll let the charger go at 125a (.25c). I figure I have 400+ full cycles on the batteries and do not see any ill effects yet. When the day comes and we come off the road I'll break the batteries down to see how much capacity has been lost.
You'll be spoiled when you implement the full use of the system and at all levels of SoC not worrying if you have enough power left in the batteries.;)
