Hitch/ Fairing cover!

When we were away at Poolsbrook last week our hitch/ fairing cover blew away, never to be seen again!  We would like to buy a new one, but would like a really large one to cover not only the hitch, handbrake and jockey wheel handle, but also the electric cable which fits into a little holder towards the back of the fairing.

With the old cover, we either had to leave the electric cable exposed, or move it from the holder and tuck it underneath the handbrake.  We would like a cover big enough to cover the lot.  This might be an impossible quest, but just thought I would ask just in case anyone knows of anything.  Would prefer to buy one than go to the trouble of making one.
