Note that the failed plug/socket that I posted was less than a year old and showed very little signs of corrosion before failure.

A smartplug is certainly better, given the increased contact area yielding lower resistance. It can therefore tolerate SOME more corrosion before heating. But --- IT IS NOT THE SOLUTION to this problem!!! These, too can fail if not kept up. The solution is clean contacts - on any type of shore power cable.
Well, I have replaced it with a Smart Plug so I'm hoping it will be just fine. We will see.Ouch; what will be different next year?

I agree. I have been checking the temperature on it regularly under load. So far so good. I do think that it could have been water ingress. We had a lot of rain last winter and I don't think it sealed very well. I will watch it very closely.If a clean, non-corroded terminal melted on the previous connector, then there may be some other weak-point in the system that manifested itself as heat at that particular point (highest resistance -- regardless of corrosion). In the past, for example, I have seen things like under-gauge wiring from the shore power inlet to a panel do this ---- at the connector.
Might be a good idea to load down the system and run an IR gun around all the pieces-parts to see if you can locate any hot spots.
Just a thought.....
