I assume the main risk would be running on a 50amp breaker to power a space heater for example?
not sure i understand what you're asking...(50amp tester)? if you are referring to this panelhttp://www.myrv.us/electric/Pg/50amp2-4.htm it shows a 2 pole 50amp breaker and 220 plug and a single pole 20amp GFCI breaker and a 20a/120v duplex. the 20 amp duplex is fed by one 120vt lead (L1). if your RV has a 30amp service cord,you could hook up to this box using a 50 to 30 amp adapter.that would give you a 30a/120v feed.that should be all the "option "that you would need.. the 20 amp 120vt duplex would be used to power a space heater. it is a misconception to think of it as 50amps of power coming from a 50 amp breaker. that is the "capacity" of the breaker in amps,and the load it will withstand from whatever devices are running on it.
this has become way more complicated than it needs to be. every one with an RV should assess the electrical power requirements of their RV and maintain a "kit" to cover whatever electrical service you encounter in an RV park.do a little research on what adapters are available,and what you may possibly need.
