Plugging 30A 5th wheel into 50A service
Will I have any problems if I plug my 30A fiver into 50A service at a RV park. I will not be drawing any more than 30A, but the park says I should pay $50 deposit to rent a "box" from them.

Well which is it? Are they the same or differant? I double checked my calculations online with NEC, and stand by their minimum requirements, none the less you have already contradicted yourself, the lack of knowledge about how electricity works makes you wonder!
The purpose of a circuit breaker is to protect the wire/circuit downstream by breaking the circuit.
If you plug a 100A device into a 20A socket, the wire/circuit between the breaker and the device will be protected because the breaker will trip.
Now, on the instream side of the breaker you could have 2Ga wire where that wire is protected upstream by a breaker designed to protect much higher Amps.
