For dry camping, my WFCO got retired.
I think the most I ever saw out of it was maybe 18 amps. That was on a single group 24 75 Ah battery. It never went in to bulk charge mode for me, ever. Not enough batteries.
It also never did a good job of topping off my battery unless I was in an RV park for a couple of weeks at a time, hooked up on a pedestal.
No thanks, I like dry camping a whole lot more. Along with an adjustable charge controller for my solar panel. Much better at topping things off.
I guess I haven't yet progressed to "Glamping", or "Glamour Camping" yet with all the bells and whistles. At that point, may as well just go get a room.
