Usually 1500 watts so a 15 amp GFI is fine to use. The better ones have two settings, 750 watts and 1500 watts.
If you are paying for the electric at a cg, and almost all do charge extra for it, you are foolish not to use it. Unless you are at a cg that meters your usage, then propane might be cheaper. They are far and few between though. Usually that is only done on seasonal or year round sites.
Try to plug it into a receptacle that has nothing else plugged in to it. That way you won't trip the breaker. If you are going to use two keep them on different circuits.
I prefer a spot that has my coffee pot, a Keurig, on the same circuit. I just shut the heater off for the couple of minutes it take to make it. You can't run anything that draws a heavy load on the same circuit as the heater. If the heater has a low setting you might get away with running something on the same circuit but all bets are off. My Keurig draws too much but have a cheap Black and Decker pot that I can get away with. A toaster will trip the breaker with heater on low also. Most of them will draw too much power.
