Wayne,
Outstanding observations!
It seems to me that, given what you are saying, AGM batteries hands-down have at least that (tremenduous?) added advantage over FLA's ... which in many cases might mean that an RV'er who switches to them might not need to spend additional $$ to replace their stock single-stage 13.8V converter. Obviously I never replaced mine ... used the saved $$$ for other RV mods.
What you mention probably is related to two things:
1) Some AGM batteries are designed to be floated in the 13.5V-13.8V range.
2) All AGM batteries intrinsically have much lower internal impedance than FLA batteries ... hence AGM batteries, if needing a charge, can also suck up pretty good charge current at only their float voltages.
