Currently available on eBay from ukcustomcovers for just £12.50... https://www.ebay.co.uk/itm/274985442159?ssPageName=STRK:MEBIDX:IT&_trksid=p2060353.m1438.l2649 I stuck one in my watch list the other day and was quickly offered a 5% discount and at £11.88 inc next day postage I couldn't resist. Certainly not heavy duty but the fit is very good and I'd say it (subjectively) blocks about 90% of light coming through into the cab. Will certainly do for keeping the dust off in the garage during the winter lay up and with a bit of reflective 'bubble wrap' underneath will do the job of more expensive thermal covers for occasional camping use
