Is there anything special about RV electrical outlets?

I know a lot of people don't like the blade style of connections and neither did I. But the reality is that they are very sound, carry the load without any problem and are UL & CSA approved. It's also the way the commercial world is wired and has been for many years.

The ones that came with my TT is more than ten years old and have powered a space heater and water heater all that time. They still work perfectly.
