BT Cruiser 5240 cover for winter storage

[Rkatona]

I am looking for a good fitting cover
for my 5240. I have tried a class c cover that fit my measurements, but it turned out to be too large. I think it is because of the BT Cruiser's shape and low profile. I am thinking that a campervan cover may be too small because of it's width. Any suggestions would be helpful.
