Since our Hurricane 29M was built with a residential fridge I want the batteries to be able to recover as quickly as possible while on shore power or with the generator running.

You will find posts on WFCO lack of performance all over various forums. I’ve seen posts about the Harris batteries that Thor puts into the coaches going bad very quickly (mine did) and Harris denying warranty claims due to converter performance. It’s quite a scam they have going because they know that the WFCO’s do eat batteries and they can deny warranty claims and get away with it. Thor doesn’t seem to care much as they keep supplying WFCO and Harris as OEM.
After our first winter storage, the Harris batteries wouldn’t take much of a charge, so I replaced the WFCO converter with a Progressive Dynamics multi-stage converter (they make a slide in replacement) and a pair of 6 volt Interstate batteries. They have been working fine. The Progressive Dynamics goes to 14.5 volts when the battery is low and then goes to 13.2 volts in maintain mode. It also will automatically go to equalize mode for periods when it’s been in maintain for awhile.
