I've ordered the PD9260CV, so that is underway. Reverse polarity: don't know, don't especially care, but thanks for advice. About 15 years ago my first 5th wheel was blowing power converters on almost every trip; I asked the repairmen and the parts people later on what the heck was wrong. They said lots of campgrounds had reversed their polarity, not knowing, and that that would blow them every time. They even sold me a polarity testing device. I am in no way an electrician; but I can positively tell you lots of them failed on me and that was the reason given.
Appreciate the help.
