I have had a WFCO 8745 running continuously since the Fall of 2012 with absolutely no problems. Temperatures have ranged from below -15 to above 120 F without a hitch. I think that it is possible that WFCO has some QC problems in the past but have improved. That said, I am not an acolyte for anyone. My friend's trailer has PD and we were troubleshooting why the battery only charged to 7 VDC. Turns out that is what the charger unit was putting out, so it looks like one side of the rectifier is open.
Does this mean WFCO good, PD bad, I don't think so. Anecdotes, no matter how heart-rending, are not data. How many WFCO are sold compared to PD? When the RV market went into the toilet, I saw far more WFCO units for sale, hadn't even heard of PD, telling me that many of the manufacturers were installing WFCO. (of course, that may be why they were going out of business) As for the frequent comments about China vs. America, ipads and iphones are both made in China, what about their quality control? Where do almost all of the components used come from?
I know, not much clarification for your question, just my two cents.
