I cannot find the details in the WFCO Ultra III manual. Does anyone know the power draw from the convertor while it is charging the battery from the TV?

I'm pretty sure that the converter is not involved in charging the the battery when hooked to the TV and your not on shore power. I believe the converter is in parallel with the TV alternator and the TV charges at 13.? just like the converter. The TV alternator is actually charging both the TV and T@B batteries, and supplying the TV power needs when the TV engine is running. That is why many TV tow packages include a larger Alternator.
