I would also add more solar. and I am happy with AGM, my built in charger is very close to the voltage my AGM wants to see, Lithium should really have a
Different Charger.
I run 180Ah AGM batteries, and 300w of solar. I can watch Satellite TV for 2-3 hours, run fantastic fan, run water pump, refreg on Gas, LED lights and still have plenty of power when we wake up in AM (70%). during the day the North Carolina sun brings that back up to 100% by early afternoon. in middle of summer 200w was enough but with panels on front slop of RV I had to try to face south when parking RV. Once the days got shorter in Sep/Oct we were getting close to not fully recovering, especially of we had much rain that day so I went with 300w. I have room and wiring for one more but never got around to it. Now I live in Central Florida so the requirements have changed, need to run AC more so less off grid camping but the sun is brighter down here so my solar requirements have gone down.
in fact when I store my rig I don't even hook it to electric. in summer its always 100% ready to go, in winter with cover on RV (and battery switch turned off, but solar is wired direct to battery) it keeps RV at 100%
