CA Traveler before you start saying it's safe to hook to a 30 to 50 I suggest you look at the way some of the 30 amp cords are connected to the inside the trailer.
My initial connection is in a metal J-box.
You may have a metal J-box but how are the wires connected inside of that box, are they just wire nuts that came come loose over time or never tight to begin with. Loose connections cause heat that raises the temp in the wires causing more resistance causing more amp draw and more heat. Eventually the wire outside the box will start to melt causing a fire hazard. If you are on a 30 and breaker like your system is designed to have you have a better chance of the breaker tripping. You don't have to have a short for a breaker to trip, if you draw over 80% of a breakers rated value for a long period of time it will trip on internal heat just like its designed to do, it's a built in safety factor. I'm not guessing on this stuff, my business was located in a town next to a COE lake and I did a lot of service calls on trailers for just this kind problem. Do what ever you want but remember there are other RVs parked close to you don't make your problem their problem.
So the RVs with a 30/50 adapter tended to burn up and those direct into 30 amp had no issues?
You can have a wire nut issue no matter what the RV is plugged into. I speculate most wire nut issues are open problems not short circuits melting 30 amp cords plugged into 50 amps.
