At least that's the way I understand it, since the converter only trickle charges the batteries you can't hurt the truck wiring because all power from your truck has to run through the converter. I'm sure someone can correct me if I'm wrong.

Your statements (Changed to red) bring up a point that I'm not certain about, so I've sent an email to WFCO to get their explanation. I don't believe that the converter has any control over or influence in charging the trailer battery during towing. I think (from what I understand about converter operation) that unless the converter is powered by 120 VAC, it does not produce any DC voltage and does not influence the voltage level that is being supplied by the tow vehicle alternator/voltage regulator. What comes through pin #4 on the trailer umbilical plug is not affected by the converter, rather it bypasses the converter and goes directly to the DC fuse panel input lugs in the power distribution center. The converter is not powered on and doesn't have any influence in DC power unless the trailer is plugged into shore power or a generator.
I'll post the answers from WFCO when they respond.
