Eventually found the site which is almost opposite the Southampton Scientific centre. The Caravan club sign is high up on a tree. The narrow lane leading down to the actual field, is a bit steep & bumpy. However, we had a quiet evening caravanning the old fashion way using our gas & battery. In the morning we had a bit of difficulty leaving the site even with our 4x4 landcruiser, but the owner did inform us afterwards that we had pitched near the swamp area which we were unaware of. Would stay there again if we were heading West and needed another one night stop over or were looking for a quiet weekend going back to basics. There is motorway noise but it's more of a background white noise which didn't bother us.
