Hi Denise, My advice would be to avoid grass whenever possible. A couple of years ago my husband and I were on holiday in our van with my parents in their van.We arrived at Knaresborough CC Site and so that we could be together we chose to go on grass as there were no adjacent spaces on hard standing - BIG MISTAKE. Although it was summer we had continual spells of really heavy rain - after a few of these we realised that the vans were sinking.The spirit levels, which had been perfectly level on pitching,were showing a definate tilt, the mud started coming through the groundsheet and within no time everything was filthy. Halfway through the holiday, after packing my father and husband off to the railway museum, my mother and I decided we could not stand the muck any more and spent a day taking down the awnings, moving the vans and putting the awnings back up on two hard standing pitches (still not adjacent but we did not care).The next morning was spent scrubbing the groundsheets,chairs and tables so that we could use them again. What I am saying is that the decision to go on grass cost us 1 and a half days of our holiday moving to hardstanding. I do not expect everything to stay pristine but when everything placed on the groundsheet is muddy when you pick it up, and walking to the car makes your shoes so muddy that the car mats are filthy etc it is not alot of fun. So unless you are off to somewhere sunny and dry I would steer clear of grass. I have an MPV and was worried that it would not be able to pull the van on a squelchy field but I took it slowly and it managed perfectly. Eileen
