Duster in the Harbor Freight Portable Garage- fits, just barely
I bought one in the fall,to park one of my cars in while I worked on the other over winter.This one is 20x11 and parked my car and motorcycle in it.It held up to this years not so harsh winter.I,ll use it for storage now!.
P.S I bought 6,3 foot anchors to hold it down.The shelter came with 8 footlong ones,not good enough.
