It sounds like you were using an adapter to plug your 30 amp cord into a 50 amp pedestal receptacle because you kept blowing the 30 amp breaker when using the 30 amp receptacle. If so, that allowed you to pull 50 amps through your 30 amp cord which it is not designed to handle and you could have easily melted a connection. Lesson here is to manage your electricity use better. If you are blowing the 30 amp breaker, reduce your usage by using propane for everything that you can and turn off 120V items that are not being used. Don't plug into 50 amps as your rig is not designed for it.
I think this is the correct answer. You were using near 30 amps all the time so you were popping 30amp breaker. You change to 50amp available so the breaker is no longer the limiting factor so the first 30amp piece of equipment is the limiting factor. I would also inspect the cord and anything else on the 30amp side of the trailer as it was seeing near max amps for a whole week.
I would also find out why you are using 30amps so much of the time. You either have other things turned on that you don't realize, or you have a problem with your AC or fan.
Nope, the 30A CB in the rig will limit the draw to 30A even with the 50/30 adapter. There is no reason to suspect that the 30A CB was defective and allowing excessive current since it was tripping.
Likely the 50A plug had better voltage or the draw changed between the 2 plugs. But either way limit the draw to 80% and yes clean all of the contacts.
