HD alternators for any particular vehicle are typically bolt-in with no modifications required. They do cost somewhat more. The labor cost would remain the same so some people choose to upgrade the alternator when/if the OEM one fails. | HD alternators for any particular vehicle are typically bolt-in with no modifications required.

Some older RVs come with DUVAC (DUal Voltage Alternator Control)((https://www.countrycoachforums.com/index.php?PHPSESSID=3ggkjl41c5lrkrerduih87oeif&topic=6840.msg34665#msg34665)) setups, which use separate voltage-sense wires for the house bank. {As far as I can tell this was a workaround from when many isolators were diode-based so the alternator could not "see" aux battery voltage on the combined circuit -- secessus} See [[https://www.dixie-electric.com/tsb/TSB_704.pdf|this TSB]]. (PDF) | ===== DUVAC ===== |

| > This Duvac system that Leese Neville came up with was a completely integrated dual battery/isolator setup that was “state-of-the-art” in ’99((diode-based isolators)) but soon was obsoleted by newer better technology.((voltage-sensing relays and DC_DC chargers))((https://www.foreforums.com/index.php?PHPSESSID=bs0n0psbr6rrvd240rv4ijvg1p&topic=33250.msg432529#msg432529)) |
