What kind of rig are you in?
Your biggest decision is where you want to park. You can park in your state row, or with your rig type, or in C-50, which is guaranteed 50amp and you can park by your rig. Actual parking spots are assigned in arrival order.
It's semi-dry camping - you'll have electric at your parking spot, but water is only at the ends of the rows, alongside the road. There is a free dump station, but once you're parked, if you're full, you'll have to pay for the honey truck to come pump you out. There is a large bath house available.
I strongly suggest bringing your toad - we usually make at least one trip to Mason City during rally week. However, it's not a requirement, as there is shuttle service that will take you just about anywhere you need to go in Forest City.
Since you're arriving on Friday, make sure to go to the Puckerbrush Days parade in town on Saturday morning and fireworks Saturday night. See what they did last year at

Definitely take advantage of the factory service opportunities while you're at the rally.
