Flooded Batteries on Float
It's been mentioned that flooded batteries just keep accepting amps seemingly forever whereas AGM's will stop accepting amps when they're full. Don't know if it's true or not but I can say that my bat...

That's where modern ever-lower-power integrated digital and analog circuits really come into their own. They generate far less heat on their own than their ancestors did so can operate in cramped quarters and not overheat, thus not needing to be auto-shutdown with temperature so soon.
I suspect that with modern power supplies it's more a matter of keeping temperatures down on and around their printed circuit boards - not so much any choke, transformer, or resistor excess heat in the power supply's output stage anymore.
As far as "RV use" is concerned, IMHO, all components of an RV's 12 volt system should be able to continue to operate well up there within both high interior coach and high exterior ambient temperatures - say operate in at least 120 degrees F temperatures at full rated power specifications. And here's the kicker - do this without fans - using air convection only ... for us drycampers that consider electrical energy as precious. BTW and FWIW, "air convection only cooling" also includes the absorption refrigerator's guts along with it's circuit boards.
An Iota cutting out at "only" 104 degrees F is a no-no in my book.
