I thought the start battery is much closer to the alternator voltage sense and therefore after a short bust of amps, they taper drastically as the starter battery is up to snuff.
Basically true. Many bars now have some kind of battery "state of charge" sensor that is an input to the "smart charging" algorithm in the PCM that determines the optimal vehicle battery voltage.
This might "maintain" the battery in your RV, but it is NOT high enough to recharge it !/
