I tried some searches on the forums for this topic and didn't have a lot of luck this morning. We have a gravel area by our driveway that I usually park the PUP over the winter. When we have the driveway plowed in the winter the PUP gets a lot of snow pushed right up against it. So this fall after winterizing I moved it to a different location, sitting on grass, giving the plow driver a lot more room to work with. Someone expressed a concern that parking the PUP on grass over the winter might cause moisture problems, more so than sitting on gravel. They had parked a car on their lawn and the floor rusted and rotted. I can't imagine that happened over one winter, and besides the PUP sits a lot higher than a car and would allow for a lot more air circulation. Has anyone seen or heard concerns or issues from a PUP spending a New England winter parked on grass versus gravel or pavement? One day I'd like to have covered parking for it, but that's a long way off.
