Very Inexpensive Battery Maintenance Charger
1.0 ampere output. 13.8 volts regulated charge limit. This unit is good for 100 amp hours worth of batteries. IMO the voltage is a tad high for a high antimony RV battery with temps 60F or higher but ...

Thanks for the detail, David.
I'm sure my ~8 year old C&D Technology AGM batteries are not capable of full capacity anymore - or at the least would be very surprised if I had them tested and they turned out to be. They've been on OEM recommended float voltage year after year while the RV is stored out in the back yard. (We're a long ways from being full-timers.)
I SOMETIMES - but often ignore/forget to - turn the float voltage off of them during hot summer days. Maybe they're in "pretty good shape" from the constant floating, but most likely far from full capacity if for no other reason than their age. I'd like to replace them with a couple of Rolls Surrette S12-160AGM batteries for a total of 290 AGM amp hours under the RV step where the current Group 29 C&Ds are, but sure hate to spend that kind of money for part time RV'ing batteries ... especially considering the shipping costs from who knows where I'd have to buy them (Canada?).
