Good reasoning for the single 100AH Li and recharging routines. I have camped when it is near freezing and the furnace ate 100 AH in a day, never mind all the other 12v draws, so I would need two of those Lis to avoid running out of AH in the night. Reasoning still comes out the same way, needing 400AH of GC2s or equivalent.
Of course it requires you to be young enough to get the 10 years to make that work!
@ BFL , is your furnace efficient ?
One thing I do is do my charging in four small sessions instead of one long charge session , that way i can crank the furnace up to full blast for a half hour while i charge the battery and that prevents the furnace from drawing the battery down, when I get done with that session I turn the furnace on low to keep it from drawing the battery down , since I had the heat up so high previously the heat lasts quite awhile and then slowly starts tapering off , that's when I crank the generator and battery charger plus dial the furnace back up to high, I just do that to help prevent drawing the battery down.
You may get away with 1 100ah lfp battery because your in a van, rather small space.
Some of us that like a little more elbow room have a few more more lfp batteries not because we don't know what we're doing but we enjoy the conveniences without the need to fire up a generator. To each their own though. ;)
