I've never worked out the $-math on this, but there may be a third economical way to bring RV batteries to full charge.
For us hit-and-run type RV campers who only stay a day or two or three at any given campsite, driving between campsites in a motorhome (as opposed to a towable) can fully charge the batteries via the main engine alternator if large enough AWG cabling runs between the alternator and the coach batteries.
Only 4-6 hours of driving brings our 230 amp hour AGM battery bank back to full. At least the built-in ammeter shows zero amps going into the batteries after this amount of driving. I assume that if the batteries will no longer accept any current from the alternator, that this means they are fully charged. Is this a bad assumption?
Our situation was like this with our previous AGM batteries for years and it's turning out to be the same regarding our new set of AGM batteries. This way of fully charging our RV batteries may not be "economical" but it certainly is "not-noticeable" dollar-wise ... since we would be driving between the campsites anyway.
