Here is a map of the campground layout from Iowa’s Dept. of Natural Resources:

This shows just one restroom in the area where folks would camp.

It occurs to me that we know the Schmidt family was camping in a tent, but the Sherwood might’ve been in a tent OR a camper, as the park map shows places for both types of camping. The Sherwins being in a camper or similar RV-like vehicle makes more sense, given the mother’s comment about storing the gun in a “secure container behind the driver’s seat.”
EDITED: Sherwins were in a tent.
DCI: Killer stayed in tent 75 yards away from Iowa family he later attacked
I agree with others here who suggested that it seems likely that AS intended to target his parents. I wonder if AS woke up early, snuck out of the tent and to his parents’ vehicle, retrieved the gun, and then, upon returning, mistook the Schmidts’ tent for the one where his parents were sleeping? Only 75 yards apart…sounds like it’d have been an easy mistake to make especially in the early morning light.
EDIT 2: Per
DCI: Killer stayed in tent 75 yards away from Iowa family he later attacked the Sherwin parents were in a separate tent next to AS’ tent. Sneaking out to the vehicle to get the gun would’ve been easy for AS to do without awakening his folks: “The killer’s parents camped next to him in a separate tent, Mortvedt said. He said that the parents have been cooperating with authorities into the investigation but said that they were unaware of any previous interaction that their son had with the Schmidt family.”
