I used Primo on Moodie drive one winter while we had some house renovations done. I had an unheated stall that was 10x20 feet, so plenty big. They give you a pass card so you can drive in and out of their secure area and access it anytime. There is no electricity in the unheated stalls, so I took out the battery and left the car there for the winter, returning a couple times to check on her. No problems at all.
