Wind out M H awnings

when booking a pitch for a motorhome I am baffled as to whether to book an awning pitch or non awning when you only have a wind out canopy awning. You would have thought that every pitch would be able to accommodate one when you only have one unit, as opposed to needing space for car and caravan . Unfortunately this is not the case and seem to varies from one site to another. We have been caught out on numberious occasions not being allowed to pull out the awning as we are not on a awning pitch. I realise for safety there has to be a sufficient gap for fire. But cars can be a fire risk too so what's the difference with the awning being out afterall its taking up the space where a car would be if you had a caravan. I appreciate caravanners need these awning pitches and they must wonder why motorhomers are having to book these pitches just to wind out their awnings. I wish the club would sort this out I have raised this with HQ .
