Storage covers for TM trailers

I recently bought a used 2002 2619 in very nice condition. At least part of the winter months I will have to store the trailer out side in pretty seveer winter weather. Does anyone know where I could purchase a good quality storage cover for this trailer?
I seen ones for HILows and folding tents, but none specifically for the TM models.

Thanks
