Lots of RVs/Vans Park here, pretty quiet. Had no issues. This Cabela’s has a dump station and water for customers, so just make sure to go in before you use it.
Stayed Saturday night and spoke to the Cabela’s staff the next day when the store opened. I was informed that RVers are allowed to stay for a few days (not weeks!) on the peripheral areas of the parking lot. There were several RVs and 5th wheel parked.
