Brifla. I also recommend that you get a 30 to 15 adapter like this:

And a AC outlet tester that will plug into it(usually at hardware stores-maybe Walmart):

I use this combination to test the campsite 30a plugin for proper operation before I connect the 30a TM power cord to it.
So far, have only found one campsite with a problem -- no ground.
I added a voltmeter to my tester(only since i had one handy):
