Charging battery with external charger
So we're about to take a trip and I just determined that out on-board charger isn't charging. It's a WFCO that's going in the trash as soon as we get home. This is the second failure on a 2012 trailer...

Yup. Converter still works. Just won't charge the battery. Same issue I had with it the first time.
Have you checked the resettable circuit breaker that's wired into the cable coming from the battery's positive terminal? If it's open there's no way the converter can charge the battery.
As far as using a stand alone charger is concerned, sure it'll work ... just turn the WFCO off. I've been doing this for several years, just leave my WFCO off and instead use a CTEK Multi US 7002 which is only a 7 amp charger, works just fine, in fact better because it does a proper 14.4 volt bulk charge which the WFCO could never achieve.
