Second, buy you a 30 to 50 amp adapter and use this if your CG pedestal has a 50 amp receptacle.  The 50 amp receptacle  will more likely have better contacts than the 30 amp.  30 amp receptacles tend to get overloaded, causing the contacts to get hot, then weaken, causing overheating of the plug.
I wonder if he is already using a 50 amp adapter and somehow drawing more than 30 amps.  One needs to be careful using a 30 amp, #10 cord and protecting it with a 50 amp breaker.
Wouldn't the coach 30 amp breaker protect everything?
Yes, except for the 30 amp rated cord if there was a 30 - 49 amp fault before the RV main breaker (which is pretty near impossible). A dead short in the cord (a more likely fault) would trip the 50 amp pedestal breaker fast enough to provide protection.
