what is the cover made on a trailer tent?

You know, it would have been really eas for you to have done a Google search for "Trailer Tent Cover" and checked a few of the descriptions, wouldn't it?

I found:

Heavy duty PVC cover

TenCate waterproof & breathable polycotton canvas

Triple layer SFS material beads water on contact affording maximum resistance to rainfall and snow

You get the idea
