If you are after a fitted winter cover for your Eriba here are the three UK links I know of, the benefit of a bespoke cover is that they will have gussets and allowances made for external fixtures, they will also have a door that will give you access into the Eriba whilst it is on.
They are a snug fit with no extra material flapping about. However they are expensive but that is reflected with the breathable material they use and the workmanship.

Top tip, if you want a cover don't leave it until the last minute when Autumn sets in as this their busiest period, if you order in summer you will get it dispatched quickly and they sometimes have money off as an incentive to buy during their quiet periods.
The Protec and the Specialised will be able to make all the necessary alterations to allow for external fixtures such as pull out awnings, bike racks and on some models the spare wheel carrier on the back, so do your home work before you order and contact them so they are aware.
The Automotive covers do not allow for external accessories and the eBay advert says they are not suitable for the taller Eribas post 2010, you would be advised to contact AL to make sure it fits
