Thanks Twoxentrix, Scalf77, Marrett n Boywonder.

I'll think ill stick with agm. the KISS rule applies to me in this case.

I leave the van on the side of my house and solar is running 24/7 as well as the fridge. I have only plugged in shore power a handful of times.

I will need to be more diligent on the batteries n charging them the proper way. And I'll need to turn off the fridge when not not in use.

Interesting. Obviously the Blue Sea plastic covered item is a fuse block, and I see fuses, breaker, but I don't see an ACR/separator although I don't recognize the last photo.

Thanks boywonder.

Consider a Battery monitor.....it will accurately tell you lots about your battery.
Victron and Xantrex both make popular models. Victron has a bluetooth version if you want to see how your batteries are doing from your phone. ..and they have a regular version for less $$.

I had my doubts when I bought one but I use it heavily; tells you exactly what's going on.

AGMs should be cycled down to 50% state of charge (SOC) for a reasonably long life. Discharging them further shortens their life.

1193, there are a number of posts about lithium conversion if you do a search. I would agree keeping the design similar (AGM/lead acid) for your described use, if what you had is satisfactory. I did build a lithium iron phosphate battery, but paused the conversion for similar reasons... ie lead acid is working, dry camping in one location for a couple days rather than week or weeks...don't have to increase complexity, DC-DC, new house charger, freezing temp issues, space constraints, etc. This may change over time....keeping it simple is a great idea....
Enjoy
