I'm no electrician, but I have been advised for safety, on several construction sites, not to use an extension cord of a smaller gauge than the cord I'm plugging into it.
By that reasoning, the best thing is to pick up up a 30-amp extension cord. I got mine at Cabela's. Using a 30-amp extension cord (with 30-amp plugs) you can also use it at older campgrounds where the electric service is inconveniently located. Or with a generator when you want the generator to be set far, far away for noise or exhaust fume control, even when you're not using a 20-amp adapter.
And you can still use the 30-amp extension cord at home by connecting the adapter to the far end of the extension cord where it goes into the 20-amp service.
