We have been running AGM for the last couple years on our 24' bunkhouse, two Weize 12v 100AH with a Zamp 230 volt portable solar panel to charge them.
Plenty of power to run the furnace all night, as well as led lights and a propane fridge. We also charge all the phones, speakers and ipads from the 12 volt outlet in the camper. We boondock in remote spots, the only time the camper is plugged in is at home. No TV or microwave.
Works great, park in the shade and put the panels in the sun. After a couple cold nights and cloudy days you start to wonder, but we have not drained the system yet. A couple hours of direct sun will charge the batteries to full, a day of clouds will bring them back up to 80-90 percent.
As my girlfriend is now self employed and fully remote working, we are thinking about upgrading for enough power to run starlink and a router. Coincidentally, that would allow us to run the AC as needed too.
Looking at server rack style LiFePo units, but will need to mount them inside due to the cold weather we regularly camp in. Will need a big inverter and more solar as well.
The only drawback to LiFePo so far is charging below freezing, but with built in heaters and BMS shutoff it seems closer to functional than just a couple years ago.
Not a fan of generators camping.
