Usually, you find only 30 and 50 Amp hook-ups at campgrounds. Generally speaking, if you are at a site with a 50-Amp hookup, there will also be a 30-Amp socket there too. If the site is 30-Amp though, it won't have the higher Amp socket. They MAY have 20-Amp outlets, and if so, they look like standard wall outlets.
You'll need a 30-Amp site to run the air conditioner, but most everything else will be fine with 20-Amps. You can buy a 30 to 20 Amp plug adapter for your power cord if all you have to supply it with is 20-Amps (like when you're at home). Only the BIG RVs need 50-Amps, and I don't know if any of our HiLos fall into that category.
You can also buy a 50-30 Amp adapter if there is any possibility that the hookup would only have a 50-Amp outlet and your cord is 30-Amp. The trailer will not pull more Amperage than it needs, so if your cord is 30-Amp, it is safe to connect to a higher Amp source. Just don't overload a 20-Amp source with a high trailer demand.
Edit: One thing that is confusing - most of the pedestals have circuit breakers that the campground would like you to turn off when you leave, so the outlets will likely not be "powered" when you arrive. I've noticed that these circuit breakers are not at all clear about which position is the "ON" setting. So, if you don't have AC power after plugging in, try flipping the breaker to the other position.
