Another "Tip".
Bring along an extra 50 foot or 100 foot extension cord (like an orange one that's used for hedge trimmers or electric power tools around the house.)
Almost every campground (campsite) has both 30 amp and 20 amp receptacles at the power post. Some even have all 3: 50, 30, and 20 amp receptacles. Now, plug your camper into the appropriate receptacle (probably the 30 amp). And then, plug in that 100 foot secondary household extension cord, and you can use it external of your camper. It won't pull anything from the camper or the electricity available for the camper.
When we run an electric heater inside the camper, it's always plugged in with an orange cord, separate from the camper. I also use the orange cord for cooking outside on our electric griddle and electric skillet. We now have 2 flat electric griddles, and if both are plugged into the camper and the air conditioner and/or the water heater turns on, it almost always pops the breakers. Using the extra electric line, there is plenty of power for anything and everything.
So, if you have a 50 or 100 foot extension cord, bring it along. You'll find it very handy, especially if you want to plug anything into power outside the camper.
