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.

Just remember that you will have a 50 breaker feeding #10 30amp rated cable, so if you have a problem ahead of the trailers 30 main breaker, you could have an electrical fire risk. Chris
IMHO that "risk" is more than offset by the reduced potential of an overheated 30A outlet on the pedestal caused by dirty or weak contacts.
I use a 50A to 30A dog-bone whenever a 50A outlet is available. It's usually in MUCH better shape than the 30A ones.
