Parking for Camper Van

This might be a rather unusual request, but I’m hoping to stay for the summer and have a camper van. I’m taking over a sublease, but I’d like to find a suitable spot to park it. It’s a Sprinter, and I can comfortably stand inside. Therefore, I need a parking area with at least 10 feet of clearance. Ideally, I’d prefer a secure location with a camera and a fence, and someone to monitor the lot. I completely understand that this might be a big ask, but I’m also fully prepared to make a significant investment to find such a place. Do any of you have any recommendations? I’ve thoroughly explored various options online, but I’m still looking for the perfect spot.
