Depending on where you go, you may want to invest in a 50A to 30A Pigtail adapter, and a 15/20 adapter that you plug your 30A plug into, so you can plug into a smaller outlet.
There are times, when you may find that the 30A outlet at a CG is not up to par, or has some age (and causes a loose connection), so you could plug into the 50A outlet (usually newer) with the adapter, and plug into that with your shore power cable.
You won't be using the 50A.....since your RV is rated at 30A....so don't count on the CG's circuit breaker doing you much good, but you've got circuit breakers in the RV that should protect it.
Sorry, can't help you with the other question....we have a MH.
Happy Camping....
