This may not always work for you at the camp ground pedestals... In order to get 50AMPS you have be using both HOT wiring from the pedestal source. Some pedestals especially those that does not have a 50A Service may be using the same hot wire that is feeding both the 30A and 20A pedestals receptacles.
Keep in mind the 30A service is wired the same as the 20A service except for the two different size circuit breakers.
A 50A Pedestal service is actually giving you two 50A circuits feeding your 50A trailer for a total of 100AMPS total...
Here is a typical pictorial showing a camp ground 50A and 30A service provider...
There are hidden dangers playing with these things as if two HOT wires are being used at the campground pedestals you can have a 240VAC potential source to deal with between the two HOT WIRES...
Having said all of this we too will use the 30A service for our trailer power source shore power connector and use a 20AMP extension cord plugged into the campground pedestal 20A service. I like to run all of the outside 120VAC items from this 20AMP service as it does not take anything from their 30A service connection. It has its own separate 20AMP circuit breaker. This is also very useful when we run a portable electric heater in the trailer. Do this alot as we can't stand the noise the propane furnace blower makes. Wakes me up every time it kicks on in the middle of the night...
