Okay, what have people mounted in their vans as an onboard battery charger?
I'm looking for a compact unit that will charge an AGM battery using
110VAC.  Not a float charger but for two situations.  First, the keep the
battery up when I'm camped where there is shore power and then second, to
charge with an external generator in the boonies. (No comments on running a
generator, I swa the thread this week, mine will be silent :))

And for info, I ran into this when looking at some stuff available for
marine use:
