To cover or not to cover!

JV has special dispensation DD😂😂

Thanks for the replies so far all - in answer to some comments: Yes the Storage area we use is  very leafy and there are some overhanging trees near to the van hence the thought about a cover.

Weather lately has been very damp to say the least and the site is surrounded by a ditch on our side and railway the other (Good for security!). 

Cleaning on our site is not a problem and indeed there is a pressure washer near the entrance for owners to use (although I would not not a pressure washer myself!) - but it gets a bit weary keeping it clean during the colder months, especially by hand! 

Taking all into account a Cover seems to be a good option for the 2 or three months over the winter period, but just wondering if there are any downfalls in using one and if so what others have experienced...Thanks all

As does ‘rinse’.

Oh dear

We used a so called breathable cover for a season but found it created a lot of mildew spots within the van, they wiped off OK but never bothered again.  We have a drive sloping to the rear offside which seems to be beneficial in so much water is laying on the roof for any length of time. Covers flap in very strong winds no matter what you do.

Never had the need to use a cover. We are fortunate  in the respect that we have always stored the van in the rear of our house, so if it's a dry day I sometimes open all the windows and hatches and get plenty of dry air inside. Maybe we have been lucky because we have never had a damp van.  We now have a German built van so let's hope our luck does not run out.

Not checking what I had said until to late. We do not store the van in the rear of the house, but of course the rear garden.  . O' dear 100 lines again.
