I see your point Frank, but what you are describing is more about properly maintaing the connector and conductors. What you said about the 30A adapter would essentially hold true for any plug, cord, or electrical connector. A bad connection will cause the resistance to rise, which will cause the current to rise (V = I X R). That said, its not about the current you are drawing, but making sure your plug or adapter is in good shape. Wouldn't that apply to any plug or electrical connections including your 50A?
As you say, assuming your connector conductors are damaged as you indicate, the restance will rise, causing heat to rise in the circuit. For example, if you are using 120V loads, you would have 4 Ohms of resistance at 30A max. If your connector was bad as you describe, your Ohms will rise accordingly and over time. if you are driving AC units, hot water heater, etc, and the connector is bad and your resistance rises to 8 Ohms, the current you could carry in the circuit will drop, while the heat will rise resulting the horror show you describe at the adapter over a PERIOD OF TIME, while the current may not rise enough to trip the 30A breaker.
It may be limited intelligence, but the way I see it, everyone should always be taking random measurements of the circuits and properly maintaining their cords, connectors, and adapters. I realize its because I am over-protective about things, but I always replace my plugs, adpaters, and cords every few years and Ohm out the circuits from a preventative maintenance standpoint to catch a rise in resistance over-time and before a problem occurs.
The way I see it, since the conductor over-use topic applies to all regularly disconnected and re-connected circuits, the question of "should you" drive your camper with a 30A adpater is not really the issue or root cause.
Am I off the reservation here? Thoughts?David Pisano

You can install one of these in each AC unit and will run both https://www.microair.net/products/ea...nt=30176048267
Do you consume anything on long...
