Hi
I would like to give a STRONG VOTE FOR caravan covers
We have had a Protec cover on our Bailey Arizona for 3 winters now.
Pros
(1) It's a good fit
(2) Keeps the caravan beautifully clean and dry
(3) Acccess to the caravan even when covered
(4) Allows enough light in to work by inside
(5) Wheel covers protect tyres from sunlight
(6) Curtains and upholstery are protected from sunlight
(7) Excellent customer service - twice sent out replacement buckles by return, free of charge
(8) Green colour blends into garden well
(9) Hopefully might discourage a potential thief a little, ie, disguises 'van and would have to be removed before 'van can be moved
Cons
(1) Expensive
(2) A bit of struggle to fit/remove, especially if it's windy
(3) Fitting/removal really needs 2 people in my experience
(4) Susceptible to damage from protrusions. Make sure all protrusions, eg aeria, chimney, jointing strips are covered
(5) Time it takes to fit/remove if the 'van is used frequently
(6) Bulky to store when off the 'van
One of our roof jointing strips wore a hole in our cover during the first winter. My wife repaired/reinforced it with a piece of the extra fabric they include. I now "pad" ALL protrusions very carefully with pipe insulation foam secured with gaffer tape and thick rubber bands. I, also, gently rounded of the corners of the aluminium roof strips with a file.
I would recommend the optional storm straps, especially if your 'van would be stored in an exposed area. The optional large storage bag is, also, useful although ours had to be replace when it tore near the handle almost immediately. The replacement was reinforced with additional material.
In answer to some of comments made above:
I do wash the 'van before putting on the cover but it does NOT need to be dry. It means that when I remove the cover the 'van is still clean and sparkling.
My cover's instructions did NOT tell me to cover the windows in any way and I have never done that or suffered any damage to the windows or paintwork. Our 'van is kept covered in an elevated position in the windy north west but still has not suffered any sort of paint or window abrasion from the cover.
Although our 'van is quite large, 7.2 metres long, my wife and I can fit the cover between us even on windy days. Our cover came with telescopic aluminium poles to help with fitting.
There is no need to get the securing straps greasy - it's just a matter of routing them sensibly.
On balance I strongly recommend Protec caravan covers. (I'm not, unfortunately, on commission from Protec) and I speak from 3 years experience.
Don't just take my word for it. If you search on ukcampsite.co.uk you will find a lot of other posters who favour caravan covers.
