Cover for a Roo 17 Expandable?

[Dema]

Hi Everybody,

We just upgraded from a pup to a Roo 17 (2015). It will overwinter in here in Iowa, outside. Should I cover it? If so, does anyone have any recommendations on the best size/make. I see people like Adcos but also want to make sure I get the right size and something that will also more than one winter here in Ned Stark country. Or maybe just, NOT cover it?

Thanks.
