Re: Shore power chargers don't make any sense to me ...
No Float on Firefly is a best case optimal reco for longevity, as with LFP
Many owners do not want the complexity designing their infrastructure to accommodate that.
In which case 13.2V is really better than anything higher, when the Indian parent co took over they raised the spec for "drop-in" marketing purposes.
Sterling Power ProCharge Ultra and ProMariner Pronautic P
are fully adjustable.
A 0.2C charge rate availability (20A per bank 100Ah) is also better for longevity, with all quality AGM, some spec 0.4C **as a minimum**,
but lower should not be that big a deal if you never have a need for shorter runtimes.
And if you're usually charging of alt, maybe they get high amps that way?
BTW if you go with Sterling BB series for precise custom-voltage DCDC charging off a regular VR that will also deliver what you want off any old shore charger - indeed any old DC source - no need to double up on the investment in fancy gear for every type of energy input.
