We don't have a wind-out awning and we don't want to get one unless we'll actually use it, so we're planning on getting a Decathlon tarp in case we need a bit of shade. But we'll need to attach it to the side of the van somehow. I saw a previous thread where these Super Suction Cups http://www.parrotsol.co.uk/index_files/Page731.htm were mentioned but the original poster didn't really come back with a review on whether they did the job. Anyone else have any experience of them and whether they'll be up to the job?
